Double generalized linear model
WebThe double hierarchical generalized linear models (DHGLMs) are especially welcome in financial economics and mathematical finance. Stochastic volatility is the main concept … WebJoint generalized linear models and double generalized linear models (DGLMs) were designed to model outcomes for which the variability can be explained using factors and/or covariates. When such factors operate, the usual normal regression models, which inherently exhibit constant variance, will under-represent variation in the data and hence ...
