Hi, my friend asked me the below question but I do not know the answer, could you help me ?   " I'm doing a basic graph to show the percent of students who graduated within each major. Something like:   Biology - 50% graduate, 50% don't graduate Art - 30% graduate, 70% don't graduate etc.   I want to show the majors that have the highest graduation percentages at the top of my graph. However, I want to figure out if there is a way to normalize the percents. What I mean is, some majors are so small they only have 3 students total. So, some majors may have a graduation rate of 66.6%, but really that just means 2 of the 3 students graduated. I want to somehow standardize the percents based off the number of students that make up each percent so that these smaller majors are weighted less. " ... View more

Hi, I have seven dummy variables to measure patient's anxiety (1=Yes, 2= No) with around 1500 observations, and I would like to do scale construction using proc factor. But I know proc factor requires continuous data, how should I do with the seven dummy variables? Can anybody show me how to do that?   Thanks! ... View more

Hi all,   I would like to select the patients with mental health diagnosis using ICD10 code. There were up to 30 diagnosis variables for each patient, I will define the patients having mental health diagnosis if the first letter of any 30 diagnosis variables is 'F', but it seems my code resulted in all missing in mental_flag, why?   array dx(30) diag1-diag30; do i=1 to 30;     if substr(dx(i),1,1)='F' then mental_flag=1;     else if substr(dx(i),1,1) notin ("F","") then mental_flag=0;     else if substr(dx(i),1,1) in ("") then mental_flag=.; end; drop i;   Thanks!     ...

Hi,   I was running proc freq for one categorical variable and a list of categories variables without specifying options "chisq" or "exact", and found SAS only print out chisq table for some variable but print out both chisq & fisher exact tables though no expected values in cells less than 5.   My question is why SAS sometimes print out chisq table only , sometimes print out both chisq and fisher exact table.   My code is like as below:   Proc freq data=data;    tables A*(B C D E F G H I M N);run;   Thanks,   Jason ...

Hi,    I am not sure whether SAS can handle more than one predictor variables in Causalmed procedure. The case is : I got a three level categorical predictor, and created two binary variables on the basis of this three level categorical predictor variable, may I include the two binary predictor variables in Causalmed procedure?   All the examples about Causalmed in SAS manual only have one predictor.   Thanks,   Joe  ...
