plot_beta: Plot beta posterior distribution

plot_betaR Documentation

Plot beta posterior distribution

Description

Plot the posterior distribution of the linear parameters beta for each context

Usage

plot_beta(
  samples,
  X = NULL,
  context.id = NULL,
  true.beta = NULL,
  title = NULL,
  subtitle = NULL,
  plot.mean = FALSE,
  plot.grid = FALSE,
  showKhat = FALSE,
  col = NULL,
  xlab.size = NULL,
  ylab.size = NULL,
  title.size = NULL,
  legend.size = NULL,
  xtick.distance = NULL,
  left.margin = 0,
  ytick.distance = NULL,
  col.border = "white"
)

Arguments

samples

an output of the function hdpGLM

X

a string vector with the name of the first-level covariates whose associated tau should be displayed

context.id

string with the name of the column containing the labels identifying the contexts. This variable should have been specified when the estimation was conducted using the function hdpGLM.

true.beta

a data.frame with the true values of the linear coefficients beta if they are known. The data.frame must contain a column named j with the index of the context associated with that particular linear coefficient beta. It must match the indexes used in the data set for each context. Another column named k must be provided, indicating the cluster of beta, and a column named Parameter with the name of the linear coefficients (beta1, beta2, ..., beta_dx, where dx is the number of covariates at the individual level, and beta1 is the coefficient of the intercept term). It must contain a column named True with the true value of the betas. Finally, the data.frame must contain columns with the context-level covariates as used in the estimation of the hdpGLM function (see Details below).

title

string, title of the plot

subtitle

string, the subtitle of the plot

plot.mean

boolean, if TRUE the posterior mean of every cluster is displayed

plot.grid

boolean, if TRUE a grid is displayed in the background

showKhat

boolean, if TRUE a message with the number of estimated clusters by context is displayed

col

string, color of the densities

xlab.size

numeric, size of the breaks in the x-axis

ylab.size

numeric, size of the breaks in the y-axis

title.size

numeric, size of the title

legend.size

numeric, size of the legend

xtick.distance

numeric, distance between x-axis marks and bottom of the figure

left.margin

numeric, distance between left margin and left side of the figure

ytick.distance

numeric, distance between y-axis marks and bottom of the figure

col.border

string, color of the border of the densities
