This calculator will calculate Hotelling'sto compare two dependent correlation coefficients with one variable in common (e.g., non-nested regression models from the same population).
Directions: To conduct the test enter the following pieces of information in the yellow cells:
- Multiple R from Model 1
- Multiple R from Model 2
- The correlation between the unstandardized predicted values from both Models 1 and 2.
- Sample size, n (note: all models should be conducted using the same sample size)
- alpha
- # of tails of test
