R bayesian regression
Webrstanarm. rstanarm is an R package that emulates other R model-fitting functions but uses Stan (via the rstan package) for the back-end estimation. The primary target audience is people who would be open to Bayesian inference if using Bayesian software were easier but would use frequentist software otherwise. Fitting models with rstanarm is ...

WebBayesian Additive Regression Trees Description. BART is a Bayesian “sum-of-trees” model. For numeric response y, we have y = f(x) + \epsilon, where \epsilon \sim N(0,\sigma^2). … WebBayesian linear regression is a type of conditional modeling in which the mean of one variable is described by a linear combination of other variables, with the goal of obtaining …
Web[4, 5, 7, 11, 20]; the most remarkable of these methods are the nonparametric Bayesian additive regression trees [5] and causal forests [4, 9].

Web12.1 Introduction. Generalized linear models (GLMs) are a class of commonly used models. In GLMs, the mean is specified as a function of a linear model of predictors, E(Y) = μ = g−1(Xβ). E ( Y) = μ = g − 1 ( X β). GLMs are a generalization of linear regression from an unbounded continuous outcome variable to other types of data: binary ...
