draw_lambda_i: Testing truncated Normal sampling

In BART: Bayesian Additive Regression Trees

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).
