desireVar function

Computes mixture normal variance

Input the desired variance, number of distributions, and mean of the distributions, returns a value of the variance of each mixture distribution.

desireVar(desVar, num_dist, means, equalWeight = TRUE)

Arguments

• desVar: Desired overall variance of mixture normal distribution.
• num_dist: Number of normal distributions.
• means: Vector of means for each normal distribution. Must equal num_dist.
• equalWeight: Should equal weights be used, only TRUE is currently supported.

Details

This function can be used to generate the inputs for the rbimod

variances when a specific variance is desired. Especially useful when attempting to simulate a mixture normal/bimodal distribution.
