free range statistics

I look into the use of Isometric Centralised Box-Cox Transformed Ratio for analysing compositional data like proportions of soil, time use or chemicals.

Drawing an annotated choropleth map of Pacific Island countries and territories.

I show how to access data from the Pacific Data Hub to draw population pyramids of Pacific Island countries and territories.

Sometimes a Twitter storm of chart-shaming is unfair, mean, and frankly misguided. I reproduce and defend a chart originally produced by FiveThirtyEight to illustrate changes over time in how nominations for US Supreme Court Justices have been voted on in the Senate.

Beware that the direction of a principal component can vary depending on the sequence of the original data.

I make a SQLite database of daily observations of Australian security prices, volumes and short positions.

An animated map of UK Royal Navy ship locations during World War I.

I reproduce the analysis of data from a recently published experiment on the impact on Australians' and New Zealanders' attitudes to overseas aid of being exposed to writing about Chinese aid in the Pacific. Along the way I muse about the Table 2 fallacy, and try to avoid it while still using multiple imputation, bootstrap and adjusting for covariates to slightly improve the original analysis.
