Extract VCMoE coefficients

Extracts expert coefficients, gating coefficients, Gaussian variance intercepts, Gaussian log-sigma local-linear slopes, Negative-Binomial theta, or all fitted coefficient blocks from a VCMoE fit.

Usage

# S3 method for class 'vcmoe'
coef(object, type = c("all", "expert", "gating", "sigma", "sigma_slope", "theta"), ...)

Arguments

object

A vcmoe object.

type

Coefficient block to return.

...

Unused.

Value

A list or array of fitted coefficient functions.

Details

For Gaussian fits, coef(fit, "sigma") returns the component-specific standard deviation function at each u_grid point, and coef(fit, "sigma_slope") returns the scaled local-linear slope of log(sigma) on the (u - u0) / h basis.

For Binomial fits, expert coefficients are on the logit success-probability scale and coef(fit, "sigma") returns NULL. For Negative-Binomial fits, expert coefficients are on the log mean count scale, coef(fit, "theta") returns the component-specific size parameter, and coef(fit, "sigma") returns NULL.
