Fitting Generalized Linear Models using bayesian inference (family = binomial)

Description

Generalized Linear Models using bayesian inference (logistic regression)

Usage

glmB(
  formula,
  data = NULL,
  graphOutput = FALSE,
  nIter = 10000,
  thin = 1,
  returnCodaSamples = FALSE,
  priorPrec = c(0.001, 0.001)
)

Arguments

formula	an object of class "formula" (or one that can be coerced to that class): a symbolic description of the model to be fitted.
data	an optional data frame containing the variables in the model. If not found in data, the variables are taken from environment(formula), typically the environment from which blm is called.
graphOutput	regression parameters graphical output (MCMC Trace and posterior density)
nIter	number of iterations
thin	thinning interval for monitors
returnCodaSamples	if TRUE, return the cosa samples output as a mcmc.list
priorPrec	precisions of alpha and beta dnorm distributions

Details

Models for glm are specified symbolically. A typical model has the form response ~ terms where response is the (numeric) response vector and terms is a series of terms which specifies a linear predictor for response.

Value

regression parameters

Examples

dtf1 <- data.frame(Y = rbinom(n = 60 ,size=1,prob = .3), X = rnorm(60, 10,2))
mod1 <- glmB(Y ~ X , data= dtf1)
dtf2 <- data.frame(Y = rbinom(n = 60 ,size=1,prob = .3), X = rnorm(60, 10,2), X2 = rnorm(60, 10,2))
mod2 <- glmB(Y ~ X + X2, data= dtf2 )
mod3 <- glmB(Y ~ X + X2, data= dtf2 ,priorPrec = c(.001, .1) )
