Instructions here: https://communities.sas.com/t5/SAS-Communities-Library/How-to-create-a-data-step-version-of-your-dat... will show how to turn an existing SAS data set into data step code that can be pasted into a forum code box using the {i} icon or attached as text to show exactly what you have and that we can test code against.   When I look at the syntax reference for Surveyfreq I do not see a WILCOXON or Plots option.   Other potential issues involve use of strata and clusters without telling the procedure any information about the primary sampling units in the sample frame.   There is no Class statement is Surveyfreq. Possibly you meant By. There is no VAR statement, TABLES requests summaries for the variable or variable combinations. or possibly you wanted Tables Stunting*HV007. ... View more
