Today, I released a new module in the Statistics Globe Hub that explains how to perform sample size calculation using power analysis.

Power analysis – A flexible simulation approach using R
https://www.nicolaromano.net/data-thoughts/power-analysis-simulation/I go through why power matters, how to use Monte Carlo simulations to estimate it, and how this approach can be useful not only to define sample size, but also to refine experimental design.

it is very easy to tell two chips apart based on their startup power consumption. reset is negated at around 6500; after that moment, code starts executing. so the part before it should depend solely on the chip.

Check out our reference list for others that cover the U.S., sub-Saharan Africa, and other sectors besides education.
Every time researchers publish their variance components they are supporting the next generation of field trials.

Last week I attended the 6th Perspectives on Scientific Error Conference at @TUEindhoven
I learned so much! About #metascience #preregistration #replicability #qrp questionable research practices, methods to detect data fabrication, #peerreview, #poweranalysis artefacts in #ML machine learning...
I'm impressed by the commitment of participants to improve science through error detection & prevention. Thanks to the organizers Noah van Dongen, @lakens @annescheel Felipe Romero and @annaveer -

Hello #statstodon! A reviewer asks me to perform a post-hoc #PowerAnalysis. I know this is generally not advised because if you replace the a priori effect size by the effect size measured in the experiment, this will introduce an erroneous relationship between the significance level of the test and the measured power.
… but does that mean that there is no proper way of measuring power retrospectively? For example, if you refrain from using the measured effect size and instead simulate a range of “a priori” effect size unrelated to the results of the test, then the dependency of the power to the significance level should not happen?

Online #workshop:
Simulation-based power analyses in (generalized) linear mixed models
17.05.2023, 10-12h CESTThe workshop will cover basics of power analysis, linear mixed models, and why the combination of both requires a simulation-based approach.
In my experience, this is for many areas of #HealthSciences and #HRQL research a key problem when designing studies.
Maybe worth a read as well:
