effect.hmr: Posterior distribution of Effectiveness for a subgroup of patients

Description

This function estimates the posterior distribution for a subgroup of patients identified with the function hmr (Hierarchical Meta-Regression).

Arguments

object: The object generated by the function hmr.
B.lower: Lower limit of bias correction. The default is 0 meaning no bias correction.
B.upper: Upper limit of bias correction. The default is 3 meaning three times bias correction.
k: Covariable number indicating the subgroup.
level: Vector with the probability levels of the contour plot. The default values are: 0.5, 0.75, and 0.95.
x.lim: Numeric vector of length 2 specifying the x-axis limits.
y.lim: Numeric vector of length 2 specifying the y-axis limits.
x.lab: Text with the label of the x-axis.
y.lab: Text with the label of the y-axis.
title.plot: Text for setting a title in the bias plot.
kde2d.n: The number of grid points in each direction for the non-parametric density estimation. The default is 25.
marginals: If TRUE the marginal histograms of the posteriors are added to the plot.
bin.hist: The number of bins in for the histograms. The default value is 30.
color.line: The color of the contour lines. The default is "black.
color.hist: The color of the histogram bars. The default is "white".
color.data.points: The color of the data points. The default is "black".
alpha.data.points: Transparency of the data points.
S: The number of sample values from the joint posterior distribution used to approximate the contours. The default is S=5000.
display.probability: Logical, if TRUE the figure display probabilities.
line.no.effect: Horizontal line used as reference for no effect.
font.size.title: Font size of the title.
