Hey!

I want to write a macro for ANOVAS that tests a number of dependent variables against one independent variable. My current version looks like this:

%MACRO anov(input_dataset= , independent_variable= , variable_list=, output_dataset= );
/* Check how man variables are in the list */ %LET M=%WORDS(&variable_list.); %DO i=1 %TO &M.; %LET var = %SCAN (&variable_list., &i.); PROC ANOVA DATA= &input_dataset.; CLASS &independent_variable.; MODEL &var. = &independent_variable.; MEANS &independent_variable.; ODS OUTPUT Summary=output1 (RENAME=(&var._Mean = Mean &var._STDDEV=STDDEV)); PROC MEANS DATA = &input_dataset. Mean STDDEV; VAR &var.; class &independent_variable.; RUN; ods output close; ODS OUTPUT means=anova modelAnova=model2; PROC ANOVA DATA= &input_dataset.; CLASS &independent_variable.; MODEL &var. = &independent_variable.; MEANS &independent_variable.; RUN; Quit; ods output close; %END; %MEND anov;

%anov (input_dataset=multiple_sclerosis,
independent_variable= ms_form,
variable_list=eq5d hp_general_health)

Unfortunately, I'm fairly new to SAS and struggling a bit here. The variable ms_form can be 1, 2 or 3. I want my output to have the name of the variable in the first column (so eq5d for the first 3, then hp_general_health) followed by the group means, and the standard derivation, the f-statistics, and the p-value. Anybody knows what exactly I should do?

Thanks in advance!

Create a format and apply it to your source data. The format should flow through the rest of the program.

 

Here's a quick intro on creating formats

And format and comment your code. It's barely legible as posted.
