summary.stan_nma function

Posterior summaries from stan_nma objects

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().

## 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.

Returns

A nma_summary object

Details

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

Examples

## Smoking cessation

# Run smoking RE NMA example if not already available
if (!exists("smk_fit_RE")) example("example_smk_re", run.donttest = TRUE)

# Summary and plot of all model parameters
summary(smk_fit_RE)
plot(smk_fit_RE)

# Summary and plot of heterogeneity tau only
summary(smk_fit_RE, pars = "tau")
plot(smk_fit_RE, pars = "tau")

# Customising plot output
plot(smk_fit_RE,
     pars = c("d", "tau"),
     stat = "halfeye",
     ref_line = 0)
