73. As described in ret 2a, r and R are basically of similar nature; the former is the correlation coefficient for simple regression, and the latter is the multiple correlation coefficient for multiple regression, e.g., a dual-parameter correlation. The ψ value is a measure of the goodness of fit which takes into account the number of substituents for correlation analysis of substituent effects. A smaller ψ value signifies a better fit. From the F value, i.e., the F-test value, the conficence level (CL) of a correlation analysis can be assessed (see, e.g., Box, G. E.; Hunter, W. G.; Hunder, J. S. Statistics for Experimenters. An Introduction to Design, Data Analysis and Model Building; John Wiley: New York, 1978).
