logitHyperPars {TestDesign} | R Documentation |
Convert mean and standard deviation into logit-normal distribution parameters
Description
logitHyperPars
is a function for calculating parameters for a logit-normal distribution, such that the distribution yields desired mean and standard deviation.
Used for sampling the c-parameter.
Usage
logitHyperPars(mean, sd)
Arguments
mean |
the desired mean. |
sd |
the desired standard deviation. |
Value
logitHyperPars
returns two values. These can be directly supplied to rlogitnorm
.
Examples
pars <- logitHyperPars(0.2, 0.1)
x <- logitnorm::rlogitnorm(1000000, pars[1], pars[2])
mean(x) # close to 0.2
sd(x) # close to 0.1
