In RadicalCommEcol/cxr: A Toolbox for Modelling Species Coexistence in R

Lotka-Volterra model with pairwise alphas, covariate effects on lambda, and pairwise covariate effects on alpha

Description

Lotka-Volterra model with pairwise alphas, covariate effects on lambda, and pairwise covariate effects on alpha

Usage

LV_pm_alpha_pairwise_lambdacov_global_alphacov_pairwise(
  par,
  fitness,
  neigh_intra_matrix = NULL,
  neigh_inter_matrix,
  covariates,
  fixed_parameters
)

Arguments

par	1d vector of initial parameters: lambda, lambda_cov, alpha, alpha_cov, and sigma
fitness	1d vector of fitness observations, in log scale
neigh_intra_matrix	optional matrix of one column, number of intraspecific neighbours for each observation
neigh_inter_matrix	matrix of arbitrary columns, number of interspecific neighbours for each observation
covariates	optional matrix with observations in rows and covariates in columns. Each cell is the value of a covariate in a given observation
fixed_parameters	optional list specifying values of fixed parameters, with components "lambda","alpha_intra","alpha_inter","lambda_cov","alpha_cov".

Value

log-likelihood value
