Tests of hypotheses on concomitant variables in linear models
The likelihood ratio test for the equality of k univariate normal populations is extended to include the case in which the means are expressed as simple linear regression functions involving two parameters. The moments of the likelihood ratio statistic are derived, and an approximation to the null distribution is obtained.
