Uses and Abuses of Regression Modeling

Perhaps of interest to R&P scientists and statisticians

[B]On the uses and abuses of regression models: a call for reform of statistical practice and teaching[/b]


"By way of our own historical examples and a brief review of mainstream clinical research journals, we describe how this perspective leads to a range of problems in the application of regression methods, including misguided "adjustment" for covariates, misinterpretation of regression coefficients and the widespread fitting of regression models without a clear purpose"

Nice try, but nobody in this cesspool cares to learn how to critically analyze a paper. They just want to bolster their ****ty, biased viewpoints

Is that why you still make excuses for people who mask up?

I don't think wearing a mask is wrong, so no excuses are needed.

But, this paper might help with developing some literacy :)

You can lead a horse to water, but you can't make it drink :(

Hence tards telling the western world 65% of your daily calories should be carbs and eating more than 60-70 grams of protein per day as a man is excessive. Don't forget to eat snacks in between every meal, so your insulin is high all day. Cuz like das healthy!!!! Canola oil, an industrial lubricant, is healthy!!! Chronic inflammation, just take a pill, brah.

riiiiiiiiiiiight.

Maybe. I haven't seen the model you're referencing. Can you share it?

More like misinterpreting conditioning and coefficient estimates to draw incorrect conclusions through table 2 fallacies :)

You don't think that people who still mask up are ignorant? Do you still mask up?

I said I didn't think it's wrong. If it's not wrong, there's nothing to "excuse".

Regardless, what does this or Frank's non-sequitor have to do with regression modeling?

The crappy thing is that high carb diet advice came originally from a huge study (I forget the name) that only included data that agreed with the hypothesis, while half of the data was discarded. Excluded data that disagreed with the hypothesis, zero adjustment for other behavioral factors. Fraudulent AF. And it screwed the world way more than any fast spreading respiratory virus or clot shot can.

Can you share the regression model and maybe link it to the abuses/mistakes referenced in the OP?

It was a harvard study paid for by the sugar producers of america, or something like that - a sugar industry lobbying group. Back then (late 60s/early 70s) there was no requirement to state who had paid for the study.

Because the study was done by 3 (I think it was 3) harvard researchers, it was accepted at face value and then cited, without anybody else doing a similar study.

So the study paid for by the sugar people concluded fat = bad and sugar = good, which then dictated policy for generations.

Did they use regression?

Why isn't it wrong for someone to still mask up? What's the reasoning, especially since they're negative side effects.

You sound upset you can't comprehend the topic at hand :(
Maybe try the circle jerk ctard threads with your fellow dimwits :)

pretty sure the way regression is taught in college is if your descriptive statistical tests are within a certain range for your model then the model is good, no considerations for anything else.

health/human body related problems seem way more complex than typical problems in other industries though. looking at a product or a process with limited variables and most things being definable and measurable is like playing a completely different game.

"all models are wrong, but some models are useful" is a great quote

This is why empirical data are best analyzed using scientifically informed generative models :cool:

I'd say you should join that other retard in the circlejerk threads, but someone knocked over a mannequin at hot topic, mall cop. Back to work!

Hmmmmmmm, all of those booster shots must lead to an increase in estrogen, because you sure are acting like a bitch.
