BePlotDiag {BGPhazard}R Documentation

Diagnosis plots for PI, U, C and Epsilon

Description

Diagnostic plots for hazard rate (PI), latent variable (U), dependence parameter (C) and parameter of the hierarchical model (Epsilon).

Usage

BePlotDiag(M, variable = "PI", pos = 1)

Arguments

M

Tibble. Contains the output by BeMRes

variable

Either "PI", "U", "C" or "Epsilon". Variable for which diagnostic plot will be shown.

pos

Positive integer. Position of the selected variable to be plotted.

Details

This function returns a diagnostics plot for the chain of the selected variable. The diagnostics includes trace, ergodic mean, autocorrelation function and histogram.

Examples




## Simulations may be time intensive. Be patient.

## Example 1
#  data(psych)
#  timesP <- psych$time
#  deltaP <- psych$death
#  BEX1 <- BeMRes(timesP, deltaP, iterations = 3000, burn.in = 300, thinning = 1)
#  BePlotDiag(BEX1, variable = "PI", pos = 2)
#  BePlotDiag(BEX1, variable = "U", pos = 3)

## Example 2
#  data(gehan)
#  timesG <- gehan$time[gehan$treat == "control"]
#  deltaG <- gehan$cens[gehan$treat == "control"]
#  BEX2 <- BeMRes(timesG, deltaG, type.c = 2, c.r = rep(50, 22))
#  BePlotDiag(BEX2, variable = "PI", pos = 5)
#  BePlotDiag(BEX2, variable = "U", pos = 4)
