Two analogies on ‘Waking Up’. The Ubiquity of Non-Informative Priors →. What is a statistical model? July 10, 2015. Brendon J. Brewer. What is a statistical model? My own views are different. Firstly, I don’t think statistical models are representations of the data at all (barring one exception, which I will discuss later). Instead, they are representations of the. Whether or not we should trust the results of an inference, which is what we usually want to know. About the values of. Is on the x-axis and.

Testing model assumptions | Plausibility Theory
https://plausibilitytheory.wordpress.com/2014/09/09/testing-model-assumptions
Hard Integrals →. September 9, 2014. Brendon J. Brewer. We’re usually taught that it’s important to test model assumptions. For example, if your inference assumes the probability distribution for the data is a normal/gaussian distribution, then you should look at a histogram of the data to see if it actually looks like a gaussian. If it doesn’t, then you have a large risk of getting wrong or misleading answers. Or so we’re told. Consider the following simple example. There is a parameter. An important qu...

Inference bait and switch | Plausibility Theory

El cebo y el anzuelo en la inferencia →. Inference bait and switch. June 8, 2015. Brendon J. Brewer. Despite the friendly atmosphere, there is still a lot to be debated, and when the topics come up, all sorts of interesting things can happen, such as the following (poorly reconstructed from memory) conversation I had a couple of weeks ago. I’ve done my best not to misrepresent my colleague’s views. ME: I agree. Additional complaints about people still using p-values in the first place. Which is something...

Inference bait and switch. Two analogies on ‘Waking Up’ →. El cebo y el anzuelo en la inferencia. June 15, 2015. Brendon J. Brewer. Esta es una traducción al español de la entrada “Inference bait and switch” que publiqué recientemente. La traducí para divertirme y practicar mi segundo idioma. Es mi primer intento de traducir algo tan complejo como esto, entonces lo siento por algún error. Muchas gracias a Patricio Maturana Russel. YO: En tu opinión, cómo se deberían usar los valores p? COLEGA: Los cientí...

The nature of probability | Plausibility Theory
https://plausibilitytheory.wordpress.com/2015/03/08/the-nature-of-probability
Publication Bias and P-Values. How many “distributions of the data” are there? The nature of probability. March 8, 2015. Brendon J. Brewer. Recently I was involved in a Twitter conversation about quantum mechanics, during which I claimed that the nature of probability has been completely solved. I was going to write a blog post about quantum theory, but my thoughts on it aren’t mature enough so I decided to focus on the completely solved nature of probability. The first main application of probability to...

What is a statistical model? Sabbatical update →. The Ubiquity of Non-Informative Priors. August 9, 2015. Brendon J. Brewer. Over on the Bayesian Philosophy. Blog, there is an interesting short post. I have previously criticised notions of “complete ignorance”. I) The phrase “at random”. For example, there are 10 balls in an urn and one is selected at random. This is a disguise for the principle of indifference. V) Assumptions of independence, such as the “iid” conditional priors you see ever...None of t...
