Local adaptation and genetic effects on fitness: Calculations for exponential family models with random effects
Charles J. Geyer, Caroline E. Ridley, Robert G. Latta +2
Random effects are implemented for aster models using two approximations taken from Breslow and Clayton [J. Amer. Statist. Assoc. 88 (1993) 9-25]. Random effects are analytically i…
Ridge Fusion in Statistical Learning
Bradley S. Price, Charles J. Geyer, Adam J. Rothman
We propose a penalized likelihood method to jointly estimate multiple precision matrices for use in quadratic discriminant analysis and model based clustering. A ridge penalty and…
Variable transformation to obtain geometric ergodicity in the random-walk Metropolis algorithm
Leif T. Johnson, Charles J. Geyer
A random-walk Metropolis sampler is geometrically ergodic if its equilibrium density is super-exponentially light and satisfies a curvature condition [Stochastic Process. Appl. 85…
