If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."

However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …

Using R: Animal model with simulated data

#artificialintelligenceOct-14-2019, 05:45:36 GMT

Last week's post just happened to use MCMCglmm as an example of an R package that can get confused by tibble-style data frames. To make that example, I simulated some pedigree and trait data. Just for fun, let's look at the simulation code, and use MCMCglmm and AnimalINLA to get heritability estimates. Now that we have some data, we can fit a quantitative genetic pedigree model ("animal model") to estimate genetic parameters. We're going to try two methods to fit it: Markov Chain Monte Carlo and (the unfortunately named) Integrated Nested Laplace Approximation.

animal model, simulated data, use mcmcglmm, (2 more...)
