my_etruncnorm function

Expected Value of Truncated Normal

Computes the means 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.

my_etruncnorm(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. Standard deviations of zero are interpreted as numerically (rather than exactly) zero, so that the untruncated mean is returned if it lies within [a, b] and the nearer of a and b is returned otherwise.

Returns

The expected values 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.
