weibull: Weibul

In LuchTiarna/PsyFuns: Package for extrapolating psychometric information

Description

Weibull function is a core type function.


It's CDF formula is: y = 2*m*s*(log(x) - log(m)) / log(2) + log(log(2))
It's PDF formula per x is: y = 2*m*s/log(2)/x
It's PDF formula per m is: y = 2*s/log(2)*(log(x)-log(m)+1)
It's PDF formula per s is: 2*m*(log(x) - log(m))/log(2)

Usage

weibull(x, params)

weibull.orig(x, params)

weibull.inverse(x, params)

## S3 method for class 'orig.cdf'
