Multivariate Logistic Models

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1995
SUMMARY When data composed of several categorical responses together with categorical or continuous predictors are observed, the multivariate logistic transform introduced by McCullagh and Nelder can be used to define a class of regression models that is, in many applications, particularly suitable for relating the joint distribution of ...

Bias of Maximum-Likelihood estimates in logistic and Cox regression models: A comparative simulation study [PDF]

open access: yes, 2003
Parameter estimates of logistic and Cox regression models are biased for finite samples. In a simulation study we investigated for both models the behaviour of the bias in relation to sample size and further parameters.

Null distribution of some goodness of fit statistics for logistic regression [PDF]

open access: yes, 1984
The null distribution moment and percentile properties of several goodness of fit statistics for logistic regression models are considered. Small sample approximations to the critical values of the statistics are evaluated for the case of a single ...

Generalized logistic models

open access: yesMathematical and Computer Modelling, 1988
Abstract A class of models indexed by two shape parameters is introduced, both to extend the scope of the standard logistic model to asymmetric probability curves and improve the fit in the noncentral probability regions. One-parameter subclasses can be used to examine symmetric or asymmetric deviations from the logistic model.
