calcpdf: Densities of univariate distributions

In baccione-eawag/EawagSchoolTools: Miscellaneous Tools for Eawag Summer School in Environmental Systems Analysis

Description

Convenience function to return probability densities of several univariate distributions.

Usage

calcpdf(x,distpar,log=FALSE)

Arguments

x	vector at which probability densities will be evaluated
distpar	distribution type and parameters (see details)
log	if TRUE returns log of density, otherwise density

Details

Argument distpar should be a character vector containing the distribution name (first element in the vector) and parameter values (subsequent elements; these are converted to numeric values automatically).

Implemented distribution types and their required parameters are:

"Uniform" : min, max
"Normal" : mean, sd
"NormalTrunc" (truncated normal distribution) : mean, sd, min, max
"Lognormal" : mean, sd (note R parameters are mean and sd of the log of the random variable)
"LognormalTrunc" : mean, sd, min, max (note R parameters are mean and sd of the log of the random variable)
"Inv" (inverse distribution) : min, max
"Exponential" : mean

Value

Probability density (or log density) at the sample points in x.
