plotConvergence {joineRML}

Plot convergence time series for parameter vectors from an mjoint object

Description

Plot convergence time series for parameter vectors from an mjoint object.

Usage

plotConvergence(object, params = "gamma", discard = FALSE)

Arguments

object

an object inheriting from class mjoint for a joint model of time-to-event and multivariate longitudinal data.

params

a string indicating what parameters are to be shown. Options are params='gamma' for the time-to-event sub-model covariate coefficients, including the latent association parameters; params='beta' for the longitudinal sub-model fixed effects coefficients; params='sigma2' for the residual error variances from the longitudinal sub-model; params='D' for the lower triangular matrix of the variance-covariance matrix of random effects; params='loglik' for the log-likelihood.

discard

logical; if TRUE then the 'burn-in' phase iterations of the MCEM algorithm are discarded. Default is discard=FALSE.
