Nonstandard likelihood-ratio limits under semidefinite rank constraints
Didier Concordet
We study likelihood-ratio tests for the hypothesis that a positive-semidefinite matrix has rank at most a prescribed value. The null hypothesis is stratified: points of maximal all…
Confidence regions for the multinomial parameter with small sample size
Djalil Chafai, Didier Concordet
Consider the observation of n iid realizations of an experiment with d>1 possible outcomes, which corresponds to a single observation of a multinomial distribution M(n,p) where p i…
A new method for the estimation of variance matrix with prescribed zeros in nonlinear mixed effects models
Djalil Chafai, Didier Concordet
We propose a new method for the Maximum Likelihood Estimator (MLE) of nonlinear mixed effects models when the variance matrix of Gaussian random effects has a prescribed pattern of…
On the strong consistency of asymptotic M-estimators
Djalil Chafai, Didier Concordet
The aim of this article is to simplify Pfanzagl's proof of consistency for asymptotic maximum likelihood estimators, and to extend it to more general asymptotic M-estimators. The m…
Explicit formulas for a continuous stochastic maturation model. Application to anticancer drug pharmacokinetics/pharmacodynamics
Djalil Chafai, Didier Concordet
We present a continuous time model of maturation and survival, obtained as the limit of a compartmental evolution model when the number of compartments tends to infinity. We establ…
