Rxy

Correlation coefficient

n

Sample size for study

Rxx

Reliability of predictor variable X

Ryy

Reliability of criterion variable Y

u

Warning

This function will not automatically save your data object. You must create the object using the assignment operator.

Note

This is the general format required for data objects used for all the meta-analysis functions in this package. If certain variables are empty (e.g., Rxx, u), then the appropriate correction is not made, but the placeholder must be there. Moderator is useful for the user to subset the data and re-run any functions.
