Having estimated a linear regression with p coefficients, one may wish to test whether m
additional observations belong to the same regression. This paper presents systematically
the tests involved, relates the prediction interval (for m= 1) and the analysis of covariance
(for m> p) within the framework of general linear hypothesis (for any m), and extends the
results to testing the equality between subsets of coefficients.
