Hi,   I am sajama. I am using DHS data for my dissertation and using SAS studio for it. I needed to calculate krushall wallis and mann whitney u test using complex sample in SAS? could you please help me on this with the codes. I am new in SAS and when I tried using surveyfreq command, something goes wrong everytime. I have already generated complex sample (CS) plan watching DHS video and I could get the frequency with CS plan but not K test, May be I am wrong somewhere in the organizing the command.    I don't have idea if I should run the complex sample command and test command in one go or saparately? I tried using the below command: proc surveyfreq data=NDHSSAS.DHS wilcoxon plots(only)=(wilcoxonboxplot); class HV007; var Stunting; where hv103=1 and HC33=1 and HC1 >=0 and HC1<=59 and HV025=1; weight WGT; cluster hv021; stratum hv022; run;   But could not get the result.  I will really appreciate your help. Thank you in advance. ... View more
