plotw {bamdit}

Plot for the conflict of evidence parameters w1 and w2

Description

Conflict of evidence plot: this plot displays the posterior distribution of the study's weights w1 and w1. These weights indicate potential conflict of evidence of the studies. The weight w1 indicates deviations with respect to the specificity and w2 to the sensitivity.

Usage

plotw(
  m,
  group = NULL,
  title = "Posterior quantiles (25%, 50%, 75%)",
  group.colors = c("blue", "red")
)

Arguments

m

The object generated by metadiag. The model object must be fitted with the options: re = "sm" and split.w = TRUE.

group

An optional argument which is a variable name indicating a group factor. If set, then the plot is colored by groups.

title

The title of the plot.

group.colors

A character vector with two color names.
