R: Variance of Truncated Normal

my_vtruncnorm {ashr} | R Documentation

## Variance of Truncated Normal

### Description

Computes the variance of truncated normal distributions with parameters `a`, `b`, `mean`, and `sd`. Arguments can be scalars, vectors, or matrices. Arguments of shorter length will be recycled according to the usual recycling rules, but `a` and `b` must have the same length. Missing values are accepted for all arguments.

### Usage

    my_vtruncnorm(a, b, mean = 0, sd = 1)

### Arguments

`a` | The lower limit for the support of the truncated normal. Can be `-Inf`.
`b` | The upper limit for the support. Can be `Inf`. `a` and `b` must have the same length, and each element of `a` should be less than or equal to the corresponding element of `b`.
`mean` | The mean of the untruncated normal.
`sd` | The standard deviation of the untruncated normal.

### Value

The variance of truncated normal distributions with parameters `a`, `b`, `mean`, and `sd`. If any of the arguments is a matrix, then a matrix will be returned.
