The BEST models and zombies on a diet
The t-test is a classical statistical procedure used to compare the means of two data sets. In 2013 John Kruschke developed a souped-up Bayesian version of the t-test he named BEST (standing for Bayesian Estimation Supersedes the t-test). Let's try out BEST as implemented in the BEST package.

# The IQ of zombies on a regular diet and a brain based diet.
iq_brains <- c(44, 52, 42, 66, 53, 42, 55, 57, 56, 51)
iq_regular <- c(55, 44, 34, 18, 51, 40, 40, 49, 48, 46)
# Calculate the mean difference in IQ between the two groups
