Kumaraswamy distribution

Quantile-parametrized Kumaraswamy density, distribution and quantile functions.

dkuma(): Kumaraswamy density, quantile-parametrized
pkuma(): Kumaraswamy distribution function, quantile-parametrized
qkuma(): Kumaraswamy quantile function, quantile-parametrized

Beta distribution

Mean-precision beta density, distribution and quantile functions (the comparison marginal).

dbetamp(): Beta density, mean-precision parametrization
pbetamp(): Beta distribution function, mean-precision parametrization
qbetamp(): Beta quantile function, mean-precision parametrization

Model fitting

Gaussian-copula marginal regression, likelihood, estimation and diagnostics.

nll_copula(): Negative log-likelihood of the Gaussian-copula marginal regression
fit_copula(): Fit the Gaussian-copula marginal regression by maximum likelihood
fit_copula_multi_tau(): Fit the model at several quantile levels, with a monotonicity/invariance check

Residuals and simulation

qresiduals(): Predictive quantile residuals
sim_copula(): Simulate from the Gaussian-copula marginal regression
