Okay, we have several factors such as SEX, INCOME, SMOKING, and EDUCATION, and let's say that I am trying to evaluate the bivariate assocation between WEIGHT AS AN *ORDINAL* VARIABLE and mortality. I am supposed to use if/then/else statement and make categories for WEIGHT, but I am supposed to treat it as an ordinal variable, instead of treating as a continuous variable. What does it mean by treating my WEIGHT variable as an ordinal variable and recode it with if/then/else statement? I understand what continuous (Tenperature, time of day, zero doesn't mean the missing value, weight, height and age)  and ordinal (i.e. grades, levels of agreement (disagree/strongly disagree. etc *interval* not the same)  variables mean. I know how to categorize with IF/THEN/ELSE statement. Now, How do I order SAS to treat the WEIGHT variable as an ordinal variable? ... View more

Hi, How do you code so that SAS assigns an equal number of data into each of the 4 different categories? I am working with AGE variable (continuous ratio variable), and I just want to categorize them into 4 categories that would give me the same sample size in each group. Sometimes, I'd like to have an equal number of data in 5, 6, 7 categories as well. People have told me that I could possibly use the statement PROC RANK but I really don't know how to use it even after I looked it up. How do I need to code so that I can achieve this? I'd like to have an output like this:       Age group                # of people in each group ----------------------------       ---------------------------------------- 0 to ?? years old                2000 people ?? to ?? years old              2000 people ?? to ?? years old              2000 people ?? to 100 years old            2000 people Thank you!

Hi, I am figuring out the mean for the variables ABD, NHD, NHJ and NHD, and I get their means in my output table. However, I want to format so that the table in the output has a separate column that indicates what ABD, NHD, NHJ and NHD stand for. I want to indicate so that ABD is for Monday, NHD is Tuesday, NHJ is for Wednesday and NHD is for Thursday. Each of ABD, NHD, NHJ and NHD is not categorized, and I do not plan to categorize (there is no need for that since all I need is the mean). How do I define (or format ) so that monday, tuesday and Wednesday and Thursday appear in a separate column on the output table? proc means data=____.____.; var ABD NHD NHJ NHD; run; Thanks, GF ...
