4 AnswersProgramming & Design1 decade agoWhen to use weight in statistic program?
I have a database over effects of treatment. For analyse I will use three variables: drug, BloodPressure-before, and BloodPressure-after. I was thinking just analyzing Delta-Bloodpressure by Drug. But my statistical professor says I should use the "Weight" function in my statistical program for "BloodPressure-before".So analyze: Analyze BloodPressure-After by Drug, weighted for BloodPressure-Before. Why is this better?
