lnLCF: Calculate the -log likelihood of data within a model.

In phenology: Tools to Manage a Parametric Function that Describes Phenology and More

Calculate the -log likelihood of data within a model.

Description

Calculate the -log likelihood of data within a model.

Usage

lnLCF(x, data, fixed.parameters = NULL, parallel = TRUE, verbose = FALSE)

Arguments

x	A named vector of parameters (mu, sd, mu_season, sd_season, a, p and OTN).
data	CMR database formated using TableECFOCF().
fixed.parameters	Parameters that are fixed.
parallel	If TRUE, parallel computing in ECFOCF_f is used.
verbose	if TRUE, show the parameters.

Details

lnLCF calculate the -log likelihood of data within a model.

Value

Return the -log likelihood of data within a model.
