Analysis of logistic growth models [PDF]

, 2001
A variety of growth curves have been developed to model both unpredated, intraspecific population dynamics and more general biological growth. Most successful predictive models are shown to be based on extended forms of the classical Verhulst logistic ...

Identifiability of multivariate logistic mixture models [PDF]

, 2014
Mixture models have been widely used in modeling of continuous observations. For the possibility to estimate the parameters of a mixture model consistently on the basis of observations from the mixture, identifiability is a necessary condition.

A Method for Compressing Parameters in Bayesian Models with Application to Logistic Sequence Prediction Models

, 2007
Bayesian classification and regression with high order interactions is largely infeasible because Markov chain Monte Carlo (MCMC) would need to be applied with a great many parameters, whose number increases rapidly with the order.

The extreme residuals in logistic regression models [PDF]

, 1985
Goodness of fit tests for logistic regression models using extreme residuals are considered. Moment properties of the Pearson residuals are developed and used to define modified residuals, for the cases when the model fit is made by maximum ...
