CORCOR: Discussion and Listing of a Computer Program to Correct the Correlation Coefficient for Restriction of Range.
Tritchler, D. L.; Pedrini, D. T.
When a correlation is taken in a sample in which the range of the variables being correlated is limited, it is often desired to apply the correlation to groups with different ranges for the variables. In such situations, a correction for restriction of range (more precisely, restriction of standard deviation) may be necessary. Considered in this paper are four cases in which correction on the correlation coefficient is possible and a computer program to perform the correlations. The program, which includes an interactive correction algorithm for explicit restriction on both variables, is listed in the article. (Author)
