Applied researchers often use tests based on contingency tables in preliminary data analysis and diagnostic testing. We show that many of such tests may be alternatively implemented by testing for coecient restrictions in linear regression systems (as a rule, employing the Wald test). This unies...

We propose a method, alternative to that of Estrella (2003, <italic>Econometric Theory</italic> 19, 1128–1143), of obtaining exact asymptotic <italic>p</italic>-values and critical values for the popular Andrews (1993, <italic>Econometrica</italic> 61, 821–856) test for structural stability. The method is based on inverting an integral...

Sequential procedures of testing for structural stability do not provide enough guidance on the shape of boundaries that are used to decide on acceptance or rejection, requiring only that the overall size of the test is asymptotically controlled. We introduce and motivate a reasonable criterion...
