The R-statistic is not related to the likelihood ratio but instead is the partial correlation between the outcome variable and each of the predictor variables. A negative value of the R-statistic implies an inverse relationship between the predictor variable and the outcome variable, but it does not necessarily mean that the likelihood ratio decreases as the predictor variable decreases. Choices A, C, and D are true statements about the R-statistic.
