In the world of research, especially in agriculture, making a discovery is not just about luck; it is about following a solid plan. This plan is called the Design of Experiments (DOE).

#Randomization was a statistical process in which a random mechanism was employed to select a sample from a population or assign subjected to different groups.

An observational study found that authors of randomized controlled trials frequently use concealment of randomization and blinding, despite the failure to report these methods - PubMed Readers should not assume that bias-reducing procedures not reported in an RCT did not occur.

Authors of #RCTs who actually apply concealed #randomization and #blinding failed to report transparently in their articles. Making correct deductions requires inferences from clues in the study, contacting authors to get definitive information.

There is still only one test In 2011 I wrote an article called "There is Only One Test" , where I explained that all hypothesis tests are based on the same framework, wh...

#statstab #458 There is still only one test

Thoughts: Downey make a good point that all/any testing ensemble does essentially the same thing.

Thoughts: A very good small sample problem solution is using permutation tests. But, there are various ways to conduct these.

MCGT SEMINAR - ROBUSTNESS IN MACHINE LEARNING BY YANN CHEVALLEYRE YouTube video by Moroccan Center for Game Theory

🌟 Seminar with Prof. Yann Chevaleyre 🌟
We had the pleasure of hosting Prof. Yann Chevaleyre, who gave an engaging #seminar on “Robustness in Machine Learning: Randomization in the Multiclass Setting”
🎥 Catch the full seminar here: www.youtube.com/watch?v=3KsK...

Our findings have important implications, as teachers shape classroom dynamics and influence the positive externalities between students.

Also so happy to share that my maternity leave started with two paper acceptances 🥰

Permutation tests are robust and powerful at 0.5% and 5% significance levels - Behavior Research Methods Recent replication crisis has led to a number of ad hoc suggestions to decrease the chance of making false positive findings. Among them, Johnson (Proceedings of the National Academy of Sciences, 110,...

Thoughts: Permutation tests are cool and useful to learn, although they come with some quirks.

Does #randomization ensures balance of risk factors between groups? Consider this:

In Denmark 860 individuals were randomly allocated to either intervention or control. Individuals were unaware of their allocation. No intervention took place. Mortality was higher in the intervention group (p=0.003)

#statstab #156 Exact and asymptotic p-values

Thoughts: An important stats lesson is to be specific with terms. Exact p-values are not the same as asymptotic p-values (what most tests report w/o specifying).

randomization / bootstrapped based statistical inference (exact p-value)

theoretical (NHST) based inference (asymptotic p-value)

#statstab #145 {infer} package: Perform statistical inference using an expressive statistical grammar

Thoughts: Great tool for teaching #randomization based inference (and #NHST), by making hypothesis testing explicit.

#statstab #101 Randomization tests make fewer assumptions [...]

Thoughts: "...makes no assumption about whether the sample is representative." Haven't heard this before, but as I've covered in #47-#48, rand tests have their own quirks.
