SP 01 Using SAS ® to Compute Partial Correlation
نویسندگان
چکیده
Partial correlation is used in many epidemiological studies and clinical trials when a researcher investigates an association involving some potential confounding factors. Partial correlation is a method used to describe the relationship between two variables when controlling for effects of one or more variables in this relationship. In SAS, several procedures such as PROC CORR, PROC REG, and PROC GLM, can be used to obtain partial correlation coefficient. This paper will illustrate how to use these different procedures to get partial correlation, and explain the difference among these procedures.
