This is convenient when you need to calculate the number of days between patient appointments, for example. Example 1, dates in wide format. In this example, the start and end dates are in different variables. Creating and recoding variables | Stata Learning Modules This module shows how to create and recode variables. In Stata you can create new variables with generate and you can modify the values of an existing variable with replace and with recode. How can I subtract one variable from another? As @Vega has already mentioned, it looks like they are both which is why, their sum is , and when you subtract, its a 0. You might want to recheck the values. share | improve this answer. answered Oct 23 '13 at Afzaal Ahmad Zeeshan Afzaal Ahmad Zeeshan.

I have two variables A & B, and I want to get A - B for a new variable called stanpiasta.com that I used generate C = A - stanpiasta.com it gives some missing values in C, when either A or B contains missing values.. For example, if A is while B is missing, it gives missing for C, even though I want C as So I want to consider those missing values as zeros & get the answer. For some reason, I cannot seem to figure out how to subtract one variable from another. I want to subtract: {{ eventTickerReleaseTimeNormal | minus: releaseTime }} - this doesn't seem to output it to say I need to get the difference between the two in order to run a Mathematical Operation in an IF statement, comparing one time to another.
