Abstract
The calculation of R(2) and the test of significance for the least squ ares regression solution through the origin are not well documented in textbooks. Many of the statistical packages compute these statistics in such a way that the researcher may easily, though inadvertently, be misled. This paper contains a detailed discussion, supplemented by an example, of the formulae required to properly calculate these statist ics. Also, recommendations for correcting misleading computer results are presented.
