In AndrewLJackson/tRophicPosition: Bayesian Trophic Position Estimation with Stable Isotopes

Function to perform pairwise comparisons between two or more posterior distributions

Description

Function to compare two or more posterior distributions and test a hypothesis, in a Bayesian context

Usage

pairwiseComparisons(df, test = "<=", print = FALSE)

Arguments

df	data frame with a collection of numerical values (posterior samples) to be compared.
test	string with the logical test to be used in comparisons. Can be <, <=, > or >=.
print	logical value to indicate whether the output should be printed or not.

Value

a symmetrical matrix with probabilities given sum(dist1 >= dist2) / length(dist1) for each comparison.

Examples

a <- rnorm(100, 2, 0.1)
b <- rnorm(100, 1.8, 0.1)
c <- rnorm(100, 2.2, 0.1)
pairwiseComparisons(list("a" = a, "b" = b, "c" = c))
