How to only output influence diagnostics panel 1 when using proc logistic

MaryA_Marion — Sun, 25 Jul 2021 01:43:23 GMT

SAS CODE (it runs ok except I have two panels of influence plots -I only want the first one)

ods graphics on;
ods select ClassLevelInfo ConvergenceStatus EffectPlot GoodnessOfFit LackFitChiSq ParameterEstimates clparmPL OddsRatios OddsRatiosPL influencePlots;
proc logistic data=throat descending plot(only)=(influence effect(x=(D) sliceby=T)) alpha=.05;
class T / param=ref;
model y = D T/ scale=none aggregate lackfit clparm=PL expb influence;
run; quit;

Thanks. MM

Hello @MaryA_Marion,

As I've just learned from the documentation of the ODS SELECT statement, you can specify quoted labels (known from output obtained with ODS TRACE ON) in requests of ODS output objects. In your example, specify "Panel 1" to restrict the influence plots to the first panel:

ods select ClassLevelInfo ... influencePlots.'Panel 1';

FreelanceReinhard gave the correct answer, but it is worth mentioning that you can also match PATTERNS of strings. Learn how to select ODS tables by using wildcards and regular expressions in SAS.

This was extremely helpful. How can I create custom panels of 2-6 plots? Thanks. MM

I have never done this, but I see three options:

Locate the ODS template used by PROC LOGISTIC for these graphs and modify a copy of it so that it includes only the plots of interest (cf. ODS Graphics Template Modification).
Create one or more (ODS output) datasets from the statistics underlying the plots of interest and create the custom graph using PROC SGPANEL based on these datasets.
If this is not a recurring task, create the graphs of the default panels separately (see the UNPACK option) and combine them as you like in a post-processing step using graphics software.

Rick,
I have found ods exclude to be more reliable; I will carefully attempt the
ods include on smaller projects. Pattern matching looks powerful. Thanks. MM
