Coefficient-versus-tau matrix for a bqmm_multi fit

Usage

# S3 method for class 'bqmm_multi'
coef(object, ...)

Arguments

object: A bqmm_multi fit.
...: Unused.

Value

A tau-by-coefficient matrix of posterior-median fixed effects, with one row per quantile.

Examples

# \donttest{
fit <- bqmm(distance ~ age + (1 | Subject), data = nlme::Orthodont,
            tau = c(0.25, 0.75), chains = 1, iter = 250,
            refresh = 0, seed = 1)
#> Warning: There were 113 transitions after warmup that exceeded the maximum treedepth. Increase max_treedepth above 10. See

#> Warning: Examine the pairs() plot to diagnose sampling problems
#> Warning: The largest R-hat is 1.19, indicating chains have not mixed.
#> Running the chains for more iterations may help. See

#> Warning: Bulk Effective Samples Size (ESS) is too low, indicating posterior means and medians may be unreliable.
#> Running the chains for more iterations may help. See

#> Warning: Tail Effective Samples Size (ESS) is too low, indicating posterior variances and tail quantiles may be unreliable.
#> Running the chains for more iterations may help. See
#> https://mc-stan.org/misc/warnings.html#tail-ess
#> Warning: Some Rhat > 1.01; chains may not have converged.
#> Warning: Some effective sample sizes < 100; consider more iterations.
