- What is Bayesianism?
- Another name for probability theory, with hat tip to the God-fearing Reverend Thomas Bayes who earned naming rights with his Eighteenth century mathematical work.
- What is frequentism?
- A walking-dead philosophy of probability which, via self-inflicted wounds, handed in its dinner pail about eighty years ago; but the inertia of its followers, who have not yet all fallen, ensures it will be with us for a short while longer.
- What is a p-value?
- Something best discussed with your urologist? Also an unfortunate frequentist measure, which contributes mightily to the great blunder mentioned above.
