A further remark on testing linear inequality constraints in the standard linear model

Abstract

In this paper we will show that the expressions obtained by Hillier (1986) for the null distribution of the likelihood ratio test of zero restrictions on nonnegative regression coefficients in the standard linear model are the same as those reported by Farebrother (1986).

Keywords:

• Kuhn-Tecker test
• Likelihod Ratio test
• Walk test
• isotonic regression
• nonnegative regression
