Bayesian Bootstrapping Correlations

Description

Efficiently draws samples from the posterior distribution of various correlation coefficients

Usage

bbcor(x, method = "pearson", iter = 5000, cores = 2)

Arguments

x	A matrix of dimensions n by p
method	Character string. Which correlation coefficient should be computed. One of "pearson" (default), "kendall", "spearman", "polychoric", "gaussian_rank", or "blomqvist" (i.e., median correlation).
iter	Numeric. How many posterior samples (defaults to 5000) ?
cores	Numeric. How many cores for parallel computing (defaults to 2)?

Value

• cor_mean: A matrix including the posterior mean

• samps: An array of dimensions p by b by iter that includes the sampled correlation matrices.

Note

NAs are removed.

Examples

Y <- mtcars[,1:2]

bb_samps <- bbcor(Y, method = "spearman")
