Only two days left to submit your abstract for this year's @mathpsych.org meeting. Some things to consider:
1. The conference is in Canada.
2. If you cannot attend in person, there is a virtual track. Consider submitting there! You can pick the track during the submission process.
See you there!

This is professors complaining about almost every component of their jobs. Teaching. Grant writing. Supervision.

I have been a part of five psychology/public health departments over the years. I wish I could go back in time and tell myself โ€” when I was really struggling and unhappy and felt like I didnโ€™t belong in the field at all โ€” how different your social experience can be from institution to institution.

A 2x2 table with the four cells:
  I   - โ€œDefault Modelโ€ x โ€œFrequentistโ€
  II  - โ€œDefault Modelโ€ x โ€œBayesianโ€
  III - โ€œBespoke Modelโ€ x โ€œFrequentistโ€
  IV - โ€œBespoke Modelโ€ x โ€œBayesianโ€

A 2x2 table with the four cells: I - โ€œDefault Modelโ€ x โ€œFrequentistโ€ II - โ€œDefault Modelโ€ x โ€œBayesianโ€ III - โ€œBespoke Modelโ€ x โ€œFrequentistโ€ IV - โ€œBespoke Modelโ€ x โ€œBayesianโ€

So much statistics discourse orbits around Bayes verses frequentist debates, but in practice Bayes verses frequentist is often a false dichotomy. Just as important as the inferential strategy is the underlying model, and how that model is specified. ๐Ÿงต

03.12.2025 05:02 โ€” ๐Ÿ‘ 51    ๐Ÿ” 11    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 3

In many cases II's default settings are chosen so that the result closely aligns with I. Not sure why we should be happy if Bayesian results align with frequentist ones...
