A NOTE ON STUDENT'S t TEST IN MULTIPLE REGRESSION.

The article presents commentary and extensions to the dangers of multicollinearity in multiple regression equations by t tests initially asserted within the research of Bruce Cohen and Damodar Gujarati in their report "The Student's t Test in Multiple Regression Under Simple Collinearity," from the September 1970 issue. The particular faults within the mechanical t test specifications are emphasized and criticisms are given regarding a lack of diagnostic methods to detect the error.
