leftparetolognormal.mle: Left-Pareto Lognormal MLE

Description

Maximum likelihood estimation of the parameters of the Left-Pareto Lognormal distribution.

Usage

leftparetolognormal.mle(
  x,
  lower = c(1e-10, 1e-10),
  upper = c(Inf, Inf),
  start = NULL
)

Arguments

x

data vector

lower, upper

Upper and lower bounds for the estimation procedure on the parameters c(shape1,sdlog), defaults to c(1e-10,1e-10) and c(Inf,Inf) respectively.

start

named vector with starting values, default to c(shape1=2,sdlog=sd(log(x)))

Value

Returns a named list containing a

coefficients

Named vector of coefficients

convergence

logical indicator of convergence

n

Length of the fitted data vector

np

Nr. of coefficients

x = rleftparetolognormal(1e3)

## Pareto fit with xmin set to the minium of the sample leftparetolognormal.mle(x=x)
