Beta ratio distribution for SciPy
The quotient of 2 independent beta-distributed random variables has a known distribution, but its closed-form expression is a little hairy [1, 2]. One Python implementation of this distribution is available from Julian Saffer [3], but it suffers from some numerical issues… »

Bayesian biostatistics procedures matching frequentist confidence intervals
Confidence intervals are commonly misinterpreted as there being, after observing the data, a 95% probability that the true parameter lies within the confidence interval. The usual explanation why this is incorrect is that the true parameter is not random, and so is either inside or… »

Unfortunately, out of the box, KaTeX only supports one font, its default Computer Modern-based font, and does not have built-in functionality for customising this. Thankfully, it is not difficult to achieve… »

The urea:creatinine ratio in SI units
It is said that a high urea:creatinine ratio is an indicator of a pre-renal cause of acute kidney injury [1]. This is usually discussed in United States units, where urea is measured as blood urea nitrogen (BUN) in mg/dL, and creatinine in mg/dL. The… »

On the credible probability of confidence intervals
Confidence intervals are commonly misinterpreted by consumers of statistics. Hoekstra et al. [1] presented 120 psychology researchers and 442 students with ‘a fictitious scenario of a professor who conducts an experiment and reports a 95% CI for the mean that ranges from 0.1 to… »
