RDISPLAY directive

Displays the fit of a linear, generalized linear, generalized additive or nonlinear model.


Options

PRINT = strings
What to print (model, deviance, summary, estimates, correlations, fittedvalues, accumulated); default mode,summ,esti

CHANNEL = identifier
Channel number of file, or identifier of a text to store output; default current output file

DENOMINATOR = string
Whether to base ratios in accumulated summary on rms from model with smallest residual ss or smallest residual ms (ss, ms); default ss

NOMESSAGE = strings
Which warning messages to suppress (dispersion, leverage, residual, vertical, df, inflation); default *

FPROBABILITY = string
Printing of probabilities for variance and deviance ratios (yes, no); default no

TPROBABILITY = string
Printing of probabilities for t-statistics (yes, no); default no

SELECTION = strings
Statistics to be displayed in the summary of analysis produced by PRINT=summary, seobservations is relevant only for a Normally distributed response, and %cv only for a gamma-distributed response (%variance, %ss, adjustedr2, r2, seobservations, dispersion, %cv, %meandeviance, %deviance, aic, sic); default %var, seob if DIST=normal, %cv if DIST=gamma, and disp for other distributions

DISPERSION = scalar
Dispersion parameter to be used as estimate for variability in s.e.s; default is as set in the MODEL statement

RMETHOD = string
Type of residuals to display (deviance, Pearson, simple); default is as set in the MODEL statement

DMETHOD = string
Basis of estimate of dispersion, if not fixed by DISPERSION option (deviance, Pearson); default is as set in the MODEL statement

SAVE = identifier
Specifies save structure of model to display; default * i.e. that from latest model fitted


No parameters


Description

RDISPLAY produces further output from a linear, generalized linear, generalized additive or nonlinear model. The PRINT option has the same settings as in the FIT directive, except that no monitoring is available. The CHANNEL option selects the output channel to which the results are output, as in the PRINT directive; this may be a text structure, allowing output to be stored prior to display. The DENOMINATOR, NOMESSAGE, FPROBABILITY, TPROBABILITY and SELECTION options are also as in the FIT directive.

   The RMETHOD option allows you temporarily to change the method of forming residuals, for the output of the current statement only, in the same way as the corresponding option in the MODEL directive sets the default method of formation. Similarly, the DMETHOD option temporarily changes the method used to calculate the residual variability to be displayed for a generalized linear model, and the DISPERSION option allows you (temporarily) to set the dispersion parameter. These again operate like the corresponding options of MODEL (except that they apply only to the current statement).

   The SAVE option lets you specify the identifier of a regression save structure; the output will then relate to the most recent regression model fitted with that structure.
