In darcyj/specificity: Calculate Environmental or Host Phylogenetic Specificity

fit_gamma_fwd_rev

Description

Fits reversible gamma distribution to x where x is a vector of data. Internal function for phy_or_env_spec() or calculate_pec_and_pval().

Usage

fit_gamma_fwd_rev(x, lower_prop = 0.1, upper_prop = 10)

Arguments

x	numeric vector.
lower_prop	float. proportion of gamma max likelihood estimator to use as lower boundary for fitting (default: 0.10).
upper_prop	float. proportion of gamma max likelihood estimator to use as upper boundary for fitting (default: 10.0).

Value

a list with par, log likelihood, and type - forward or reverse. for reverse, also returns mx which is max(x), needed for reversing quantiles.
