Distribution properties

Moments, parameters, linear moments (L-moments), and log-likelihood of a distribution() object.

Usage

dist_moments(d)

dist_params(d)

dist_lmoments(d)

dist_log_likelihood(d, data)

Arguments

d

a corehydro_dist object from distribution() or dist_fit().

data

numeric vector of observations.

Value

dist_moments() returns a named numeric vector (mean, median, mode, sd, skewness, kurtosis, minimum, maximum; entries are NaN where undefined). dist_params() returns the parameter vector named with the family's short-form parameter names. dist_lmoments() returns the first four L-moments (errors for families without L-moment support). dist_log_likelihood() returns a single numeric value.

Examples

d <- distribution("Normal", c(100, 15))
dist_moments(d)
#>     mean   median     mode       sd skewness kurtosis  minimum  maximum 
#>      100      100      100       15        0        3     -Inf      Inf 
dist_params(d)
#>   µ   σ 
#> 100  15
