This paper distinguishes between the principles upon which testing statistical hypotheses may be based and the practical methods these principles generate. Seber's (1964) conclusion that the Wald, Lagrange Multiplier and Likelihood Ratio Principles all yield the same test statistic for linear...

This paper considers the relations between the classical identifiability test statistic and corresponding significance tests of the coefficients of endogenous variables of one equation of a linear interdependent system in the context of Generalized Classical Linear (GCL) estimation. Known...

This note applies the traditional analysis of specification error to the Cox-tests for separate regression models. Incorrect inclusion of variables in the alternative model leads to consistent tests of the null, whereas incorrect exclusion of variables from the alternative may render the tests...

The first paper demonstrates that Theil's (1961) minimum error variance criterion is asymptotically valid for choosing between non-nested non-linear regression models, as long as one of the models is 'true'. The second paper shows that when the null and alternative hypotheses are separate...

This paper seeks to distinguish the principles upon which testing of statistical hypotheses may be based and the practical method which these principles generate. Six examples are given for the case of nested hypotheses as illustrations. The concept of an artificial model is analyzed. When...

This paper is concerned with the problem of testing one form of covariance structure against another in a normal linear regression. All point-optimal tests recently proposed by King and his associates can be interpreted as special cases of the Cox test for non-nested hypotheses. This provides a...

This paper derives a complete system of commodity-expenditure and money demand equations. This approach seeks to: 1) unify the treatment of joint intertemporal decisions regarding the allocation of income and savings to expenditures on commodities; 2) accommodate a treatment of durable goods; 3)...

This paper demonstrates that the extended linear expenditure system with durables (DELES) satisfies first-order conditions for local unidentifiability, and discuss alternative methods that might be used to achieve identifiability, as well as their implications. Estimates are presented using...

It is argued that the general formulation of point-optimal tests, as summarized in King (1988): i) makes use of a benchmark which is excessively stringent; ii) fails to integrate the method with traditional testing methods; iii) uses data to form a specific null hypothesis; iv) offers no...
