WR 2) Using the contents panel on the left. Look in the details and syntax of the LOGISTIC procedure.

            - How does PROC LOGISTIC handle, by default, observations with missing values in the response?

            - Name three ODS graph options that are available with proc logistic.

            - What is the statement and option to get the odds ratio and the profile-likelihood confidence limits for the odds ratio?

Explanation / Answer

Any observation with missing values for the response, offset, strata, or explanatory variables is excluded from the analysis; however, missing values are valid for variables specified with the MISSING option in the CLASS or STRATA statement

b)
The ODS GRAPHICS statement enables ODS to create graphics. By default, ODS Graphics is not enabled. You can enable ODS Graphics by using either of the following equivalent statements:
ods graphics on;
ods graphics;

To disable ODS Graphics, specify the following statement:
ods graphics off;

c) use oddsratio in the proc

an example is

ods graphics on;
proc logistic data=Neuralgia plots(only)=(oddsratio(range=clip) effect);
class Treatment Sex /param=ref;
model Pain= Treatment Sex age;
oddsratio Treatment;
oddsratio Sex;
oddsratio age;
contrast 'Pairwise' Treatment 1 0,
Treatment 0 1,
Treatment 1 -1 / estimate=exp;
contrast 'Female vs Male' Sex 1 / estimate=exp;
run;
ods graphics off;
