calc_qqplot: QQ-Plot Calculator

In samplr: Compare Human Performance to Sampling Algorithms

QQ-Plot Calculator

Description

Estimates values for a QQ plot of Empirical values against Theoretical values from a normal distribution, for either the chain points or the distances between successive points. Optionally, returns a plot as well as the values.

Usage

calc_qqplot(chain, change = TRUE, plot = FALSE)

Arguments

chain	Vector of n length, where n is the number of trials or sampler iterations
change	Boolean. If false, it calculates a qqplot of the given chain. If true, it creates a chain of step sizes.
plot	Boolean. Whether to plot the QQ plot or just return the values.

Value

A list with the theoretical and empirical quantiles, and the intercept and slope of the line connecting the points

Examples

set.seed(1)
chain1 <- sampler_mh(1, "norm", c(0,1), diag(1))
calc_qqplot(chain1[[1]], plot = TRUE)
