Fit_dist_parameter: Returns adjusted distribution parameters

In EnviroPRA: Environmental Probabilistic Risk Assessment Tools

Description

Returns the distribution parameters adjusted for by maximum likelihood (mle) for the following distributions: "normal","log-normal","geometric","exponential","Poisson", "cauchy" , "logistic" and "weibull"

Usage

Arguments

x	A numeric vector of length at least one containing only finite values (non-censored data)

Value

normal	Fitted Mean and sd for a normal distribution
'log-normal'	Fitted Meanlog and sdlog for a log-normal distribution
geometric	Fitted prob for a geometric distribution
exponential	Fitted rate for a exponential distribution
Poisson	Fitted lambda for a exponential distribution
cauchy	Fitted location and scale for a Cauchy distribution
logistic	Fitted location and scale for a Logistic distribution
weibull	Fitted shape and scale for a weibull distribution
