## Give your R charts that Wes Anderson style

March 26, 2014
By

I'm a big fan of Wes Anderson's movies. I love the quirky characters and stories, the distinctive cinematography, and the unique visual style. Now you can bring some of that style to your own R charts, by making use of these Wes Anderson inspired palettes. Just choose your favourite Wes Anderson film or short: Install the wesanderson pallettes package,...

## Accessing iNaturalist data

March 26, 2014
By

The iNaturalist project is a really cool way to both engage people in citizen science and collect species occurrence data. The premise is pretty simple, users download an app for their smartphone, and then can easily geo reference any specimen they see, uploading it to the iNaturalist website. It let's users turn casual observations into meaningful...

## Using R: quickly calculating summary statistics from a data frame

March 25, 2014
By

A colleague asked: I have a lot of data in a table and I’d like to pull out some summary statistics for different subgroups. Can R do this for me quickly? Yes, there are several pretty convenient ways. I wrote about this in the recent post on the barplot, but as this is an important

## Random Love

Anyone who considers arithmetical methods of producing random digits is, of course, in a state of sin (John von Newman) Ms. Positive and Mr. Negative live in a one-dimensional world and are falling in love. But beginnings are not always easy. They have a big problem: none of them like the other’s neighborhood. Ms. Positive

## Stochastic search variable selection in JAGS

March 22, 2014
By

Stochastic search variable selection (SSVS) identifies promising subsets of multiple regression covariates via Gibbs sampling (George and McCulloch 1993). Here’s a short SSVS demo with JAGS and R. Assume we have a multiple regression problem: We suspect only a subset of the elements of $\boldsymbol{\beta}$ are non-zero, i.e. some of the covariates have no effect. Assume $\boldsymbol{\beta}$...

## Normality and Testing for Normality

How do we test for normality, and are normality tests really sensitive in the tails?

## Frequentist German Tank Problem

The German Tank Problem: The Frequentist Way Many things are given a serial number and often that serial number, logically, starts at 1 and for each new unit is increased by 1. For example, German tanks in World War II had several parts with serial numbers. By collecting...

## Stop using bivariate correlations for variable selection

March 19, 2014
By

Stop using bivariate correlations for variable selection Something I've never understood is the widespread calculation and reporting of univariate and bivariate statistics in applied work, especially when it comes to model selection. Bivariate statistics are, at best, useless for multi-variate model selection and, at worst, harmful. Since nearly all...
