You might notice that the editor. Proc reg is not part of Base SAS, It is. The following statements can be used interactively without reinvoking PROC REG : ADD, DELETE, MODEL, MTEST, OUTPUT, PAINT, Outout, PRINT, REFIT, RESTRICT, REWEIGHT, and TEST. By default, the DFBETAS axis is chosen independently for each panel. However, because of its popularity, we will use.




The PROC REG statement is required. If you want to fit a model to the data, you must also use a MODEL statement. If you want to use only the PROC REG options, you do not need a MODEL statement, but you must use a VAR statement. Note that any option specified in the PROC Otput statement applies to all MODEL statements. Using the ALL option in the PROC REG statement is equivalent to specifying ALL in every MODEL statement. The ALL option also implies the CORRSIMPLEand USSCP options.

The value must be between 0 and 1; the default value of 0. This option affects the PROC REG option TABLEOUT; the MODEL options CLB, CLI, and CLM; the OUTPUT statement keywords LCL, LCLM, UCL, and UCLM; the PLOT statement keywords LCL. You can use this data set to add features to the traditional graphics that you request with the PLOT statement. Features provided in this data set are applied to all plots produced in the current run of PROC REG. Special SAS Data Sets. The default graphics-catalog is WORK.

If you do not specify this option, requested plots are created on a high-resolution graphics device. Note that this option temporarily disables the Output Delivery System ODS ; see. Using the Output Delivery System. If you want to create a permanent SAS data set, you must specify a two-level name refer to the section "SAS Files" in SAS Language Reference: Concepts for more information about permanent SAS data sets.

The standard errors for ridge regression estimates and IPC estimates are limited in their usefulness because these output options in proc reg 656 are biased. This option is available for all model selection methods except RSQUARE, ADJRSQ, and CP. The factors are the diagonal elements of the inverse of the correlation matrix of regressors as adjusted by ridge regression or IPC analysis. The procedure computes parameter estimates by using all but the last m principal components.

Prooc you specify only one plot request, you can omit the parentheses around the plot request. Here are some examples: You must enable ODS Graphics before requesting plots, as shown in the following example. For general information about ODS Graphics, see. Statistical Graphics Using ODS. For jobs otput more than one MODEL statement, plots are produced for each model statement.

The global-options apply to all plots generated by the REG procedure, unless it is altered by a oktput. The following global plot options are available: specifies that the LABEL option be applied to each plot that supports a LABEL option. See the descriptions of the specific plots for details. This option is useful when you use more than one MODEL statement.

By o;tions, only points used in constructing the SSCP matrix appear on plots. The following adjrsq-options are available for models where you request the RSQUARE, ADJRSQ, or CP selection method: optiobs that the model number corresponding to the one displayed in the "Subset Selection Summary" table be used to label the model with the largest adjusted R-square statistic at each value of the number of parameters. The following aic-options are available for models where you request the RSQUARE, ADJRSQ, or CP selection method: requests that the model number corresponding to the one displayed in the "Subset Selection Summary" table be used to label the model with the smallest AIC statistic at each value of the number of parameters.

The following bic-options are available for models where you request the RSQUARE, ADJRSQ, or CP selection method: requests that the model number corresponding to the one displayed in the "Subset Selection Summary" table be used to label the model with the smallest BIC statistic at each value of the number of parameters. If you specify the LABEL option, then points deemed output options in proc reg 656 influential are labeled.

If output options in proc reg 656 do not specify an ID variable, the observation number within the current BY group is used as the label. If you specify one or more ID variables in one or more ID statements, then the first ID variable you specify is used for the labeling. For models where you request the RSQUARE, ADJRSQ, or CP selection, reference lines corresponding to the equations andwhere is the number of parameters in the full model excluding the intercept and is the number of parameters in the subset model including the interceptare displayed on the plot of versus.

For the purpose of parameter estimation, Hocking suggests selecting a model where. For the purpose of prediction, Hocking suggests the criterion. The following cp-options are available for models where you request the RSQUARE, ADJRSQ, or CP selection optiions requests that the model number corresponding to the one displayed in the "Subset Selection Summary" table be used to label the model with the smallest statistic at each value of the number of parameters.

For other selection methods, line plots of these statistics as function of the selection step number are displayed. This option applies only to the RSQUARE, ADJRSQ, and CP selection methods. Since these labels are typically long, LABELVARS is supported only when the panel is unpacked. Separate plots are produced for each of the six fit statistics. For models where you request the RSQUARE, ADJRSQ, or CP selection, two reference lines corresponding to the equations andwhere is the number of parameters in the full model excluding the intercept and is the output options in proc reg 656 of parameters in the subset model including the interceptare displayed on the plot of versus.

Mallows suggests that all subset models with small and near be considered for further study. Note that each panel contains at most six plots, and multiple panels are used in the case where there are more than six regressors including the intercept in the model. By default, the DFBETAS axis is chosen independently for each panel. If you also specify the UNPACK option, then the same DFBETAS axis is used for each regressor.

If you specify one or more ID variables on one or more ID statements, then the reb ID variable you specify is used for the labeling. If you specify the LABEL option, then these influential observations are labeled. Note that you can also request individual plots in the panel by name without having to unpack the panel. If you specify the UNPACK option, then all partial plot ooutput are unpacked. The upper plot in the panel is a scatter plot of the residuals.

The lower plot shows the data overlaid with the regression line, confidence band, and prediction band. This nonparametric fit is a ouptut fit that uses local linear polynomials, linear interpolation, and rwg smoothing parameter selected that yields a local minimum of the corrected Akaike information criterion AICC. The SMOOTH option is not supported when a FREQ statement is used.

If you specify label option, points deemed far-outliers are labeled. Each nonparametric fit is a loess fit that uses local linear polynomials, linear interpolation, and a smoothing parameter selected that yields a local minimum of the corrected Akaike information criterion AICC. This plot "shows how much variation in the data is explained by the fit and how much remains in the residuals" Cleveland The VIF values for each coefficient are connected by lines and are displayed in the upper plot in each panel.

The points corresponding to the standardized estimates of each coefficient are connected by lines and are displayed in the lower plot in each panel. By default, at most 10 coefficients are represented in a panel and multiple panels are 6556 for models with more than oytput regressors. By default, these axes are chosen independently for the regressors shown in each panel. The traces of the VIF statistics and standardized estimates are shown in separate plots. The following rsquare-options output options in proc reg 656 available for models where you request the RSQUARE, ADJRSQ, or CP selection method: requests outpuh the model number corresponding to the one displayed in the "Subset Selection Summary" table be used to label the model with the largest R-square statistic at each value of the number of parameters.

Observations whose studentized residuals lie outside the band between the reference lines are deemed outliers. Observations whose leverage values are greater than the vertical referencewhere is the number of parameters excluding the intercept and is the number of observations used, are deemed influential Ib If you specify forex com reviews 55 LABEL option, then points deemed as outliers or influential are labeled. The following sbc-options are available for models where you request the RSQUARE, ADJRSQ, or CP selection method: requests that the model number corresponding to the one displayed in the "Subset Selection Summary" table be used to label the model with the smallest SBC statistic at each value of the number of parameters.

If ODS Graphics is in effect see the section ODS Graphicsthen ridge regression plots are automatically prpc. These plots consist of panels containing ridge traces how do you buy a put option screener the regressors, with at most eight ridge traces per panel. The default value is machine dependent but is approximately 1E 7 on most machines. This option is rarely needed. Singularity checking is described in the section Computational Methods.

Here are some examples:. Only plots specifically requested are displayed. You request statistics in addition to the default set by including the keyword DEFAULT in the plot-statistics list. The following adjrsq-options are available for models where you request the RSQUARE, ADJRSQ, or CP selection method:. The DFBETAS statistics for each regressor are displayed on separate plots.




Introduction to the Output Statement in SAS


The REG Procedure Chapter Table of requested statistics available for output through output data sets the ALPHA= option in the PROC REG or MODEL statement. Lesson Proc Reg Proc reg uses an option in the proc statement, "outest=", Another statement in proc reg is the output statement. The OUTPUT statement creates a or TYPE=SSCP data set is used as the input data set for PROC REG. You can specify the following options in the OUTPUT statement.
