By default, proc corr uses pairwise deletion for missing observations, meaning that a pair of observations one from each variable in the pair being correlated is included if both values are non-missing. The hsb2 data set was used in this example, and the code used is given below. This graph shows you the strength and direction of the relationship between the two variables just like the correlation coefficient. If the distribution of the variable is skewed, you must transform it. I hope it makes sense. If you use the nomiss option on the proc corr statement, proc corr uses listwise deletion and omits all observations with missing data on any of the named variables. Also, you can use either continuous or dichotomous e. How to find correlation between variable?
