Influence Analysis of Robust Wald-type Tests
Abhik Ghosh, Abhijit Mandal, Nirian Martin +1
We consider a robust version of the classical Wald test statistics for testing simple and composite null hypotheses for general parametric models. These test statistics are based o…
Best prediction under a nested error model with log transformation
Nirian Martin, Isabel Molina
In regression models involving economic variables such as income, log transformation is typically taken to achieve approximate normality and stabilize the variance. However, often…
Generalized Wald-type Tests based on Minimum Density Power Divergence Estimators
Ayanendranath Basu, Abhijit Mandal, Nirian Martin +1
In testing of hypothesis the robustness of the tests is an important concern. Generally, the maximum likelihood based tests are most efficient under standard regularity conditions,…
Robust Tests for the Equality of Two Normal Means based on the Density Power Divergence
Ayanendranath Basu, Abhijit Mandal, Nirian Martin +1
Statistical techniques are used in all branches of science to determine the feasibility of quantitative hypotheses. One of the most basic applications of statistical techniques in…
Wald type and Phi-divergence based test-statistics for isotonic binomial proportions
Nirian Martín, Raquel Mata, Leando Pardo
In this paper new test statistics are introduced and studied for the important problem of testing hypothesis that involves inequality constraint on proportions when the sample come…
Phi-divergence statistics for the likelihood ratio order: an approach based on log-linear models
Nirian Martín, Raquel Mata, Leandro Pardo
When some treatments are ordered according to the categories of an ordinal categorical variable (e.g., extent of side effects) in a monotone order, one might be interested in knowi…
