summary.stan_nma

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

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)
