Is there a way to test whether the correlation coefficient between two variables with a shard third variable is significantly different, if the sample sizes are different?
Here is the case, specifically. Variable A and Variable B have the same number of observations, but Variable C has less. I would like to test if Variable B has a significantly different correlation with Variable A, compared to Variable C. A fisher r to z can do this, but only if there is a equal number of observations for all variables. That is not the case here. Is there a similar test that can be done?
Many thanks in advance!
