draw_lambda_i {BART}R Documentation

Testing truncated Normal sampling

Description

Truncated Normal latents with non-unit variance are necessary for logistic BART.

Usage

draw_lambda_i(lambda, mean, kmax=1000, thin=1)

Arguments

lambda

Previous value of lambda.

mean

Mean of truncated Normal.

kmax

The number of terms in the mixture.

thin

The thinning parameter.

Value

Returns the variance for a truncated Normal, i.e., N(mean, lambda)I(tau, infinity).
