Between The Binary Response Y And An Ordered Categorical Explanatory Variable X (Doses) Against The Alternative Hypothesis Of An Increase Dose-Response Relationship Between A Response Variable Y And X (Doses). The Properties Of These Test Statistics Are Studied. This New Family Of Test Statistics Is Based On The Family Of Φ-Divergence Measures And Contains As A Particular Case The Likelihood Ratio Test. We Pay Special Attention To The Family Of Test Statistics Associated With The Power Divergence Family. A Simulation Study Is Included In Order To Analyze The Behavior Of The Power Divergence Family Of Test Statisticsengjournal articlehttp://www.tandfonline.comhttp://www.tandfonline.comrestricted access519.22Phi-Divergence Test StatisticIsotonic RegressionResponse VariableExplanatory VariableStatistics & ProbabilityEstadística matemática (Matemáticas)1209 Estadística
