    Once a week I send a co-authoring clinician the Datasaurus Dozen as a reason why I won't publish a correlation paper with only coefficients and now visualization. This week is no different.

    J.R.R. Tolkien knew what he was doing. The secret to getting many things done is to think of each one of them as a procrastination strategy for avoiding the others.

    . c'est pire que dans mon souvenir (facteur 16 Vs 12) "If u have 80% pwr to estimate the main effect, u have 10% pwr to estimate the interaction ... u need 16 times the sample size to estimate an interaction than to estimate a main effect"

    If your field: i) tests hypotheses, ii) rewards successful hypotheses with career advancement, and iii) has no stringent mechanisms to prevent researcher biases influencing the evaluation of hypothesis tests, then I'm sorry to say that publication bias exists in your field

    I spent four years learning to run efficient regression analyses in R. Now I've written them into some handy functions so you won't have to.

    Terrific commentary by on ANDROMEDA study, raising serious questions about how Hardwicke and Ioannidis handled their survey of signatories to the 'end of significance' letter.

    New approach to antidoping efforts? You know when we see a performance that we "feel" just isn't clean? Well, new study with Bayesian modelling may add statistical confirmation to this "feeling" via doping vs. clean performance analysis. Interesting.

    : Is your QQ-plot generated from a normally distributed process? Draw random data from a norm dist of the same length as your data set over & over. This will give you a good idea of how a normal QQ-plot should look. Try it with `ggpubr::ggqqplot()` for easy plots

    Funnel plots are often used to assess publication bias in meta-analysis, but these plots only visualise *small study* bias, which may or may not include publication bias. Here's a guide on making contour-enhanced funnel plots in , which better visualise publication bias

    If more scientists calculated confidence distributions, they would realise that a point estimate is a value in which you have zero confidence.

    Today, we had our first class of "Critical Thinking: Exploring the Science behind the News". This is why our class matters. We opened with this jaw-dropping example. Without reading further: how did the researchers study this? What is the science behind the news? 1/ (corrected)

    There are many reasons for not using NHST/p-values, but people keep using them. I sought a simple no-brainer explainer and ended up using these slides in class. The explainer started with a refresher on how sample size is calculated. 1/n
