plot_Geweke: Plot Geweke statistic.

In hplieninger/mpt2irt: Bringing Multinomial Processing Tree Models To Item Response Theory To Investigate Response Styles

Description

Plot a histogram of the Geweke convergence diagnostic.

Usage

plot_Geweke(fit, parameter = "beta", D = 1, frac1 = 0.1,
  frac2 = 0.5, plot = TRUE, ...)

Arguments

fit	a fitted object from fit_irtree or preferably from tidyup_irtree_fit. person) or a numeric value specifying the trait value used to plot response styles (e.g., trait=0 for an average person)
parameter	Character. The group of parameters for which the stistic is to be calculated. Using the empty vector ("") uses all parameters in fit.
D	Numeric. If the plot should be grouped according to different types of parameters, D should be equal to the number of different types of processes (e.g., D = 4) for a 1/2/3/ect-dimensional "ext" model or D=3 for a 1/2/ect-dimensional "Boeckenholt2012" model)
frac1	fraction to use from beginning of chain
frac2	fraction to use from end of chain
plot	Logical. Either return a histogram or the results.
...	Optional arguments passed to hist.
