summary.stan_nma {multinma}

Posterior summaries from stan_nma objects

Description

Posterior summaries of model parameters in stan_nma objects may be produced using the summary() method and plotted with the plot() method. NOTE: To produce relative effects, absolute predictions, or posterior ranks, see relative_effects(), predict.stan_nma(), posterior_ranks(), posterior_rank_probs().

Usage

## S3 method for class 'stan_nma'
summary(object, ..., pars, include, probs = c(0.025, 0.25, 0.5, 0.75, 0.975))

## S3 method for class 'stan_nma'
plot(
  x,
  ...,
  pars,
  include,
  stat = "pointinterval",
  orientation = c("horizontal", "vertical", "y", "x"),
  ref_line = NA_real_
)

Arguments

...

Additional arguments passed on to other methods

pars, include

See rstan::extract()

probs

Numeric vector of specifying quantiles of interest, default c(0.025, 0.25, 0.5, 0.75, 0.975)

x, object

A stan_nma object

stat

Character string specifying the ggdist plot stat to use, default "pointinterval"

orientation

Whether the ggdist geom is drawn horizontally ("horizontal") or vertically ("vertical"), default "horizontal"

ref_line

Numeric vector of positions for reference lines, by default no reference lines are drawn

summary

Logical, calculate posterior summaries? Default TRUE.

Details

The plot() method is a shortcut for plot(summary(stan_nma)). For details of plotting options, see plot.nma_summary().

Value

A nma_summary object
