I’m a data scientist that builds ML models for a living. You’ve twice now tried to explain how fitting a model works in response to me stating that regression “metrics” are not well suited to describing classification “efficacy”. If anyone

Perhaps this can serve as just a single leg of a larger combination though

In most modern ML circles “regression” analysis refers to the prediction of continuous variables whereas “classification” refers to the estimation across discrete outputs. This is true even for “logistic regression”. What I said was that re

Yes but the prompt here states that all we know is the probability is either 0.55 or 0.45. By definition this is the best model you can produce.

Kind of funny but wouldn’t you want to just maximize(distance_left, distance_right) if you wanted the center? Edit: no, derp, just walked into the same problem lol. Maximize the min should work though

by jncfhnb 2y ago
No, you want your model to be well calibrated. If the model accurately assessed a 0.55 probability of going blue, then that is what you want. People who try to correct for “unbalanced classes” and contort their model to give polarizing pred

Statistics does not require asserting causality.

Classification models break down to regression problems under the hood, but regression metrics are not good tools to evaluate the efficacy of classification models.

A mixed model is not relevant here. A simple linear regression with one variable will achieve exactly the same results. Coding it as -1 and 1 has no difference to coding it as 0 and 1. You just stuff the rest into the intercept. You would a

by jncfhnb 2y ago
When you’re making a linear regression you’re minimizing the sum of squared error which is 1:1 with R2. That is, you’re getting the best possible R2 achievable with a line. The reason we do that is because we are assuming the errors are nor
977.
by jncfhnb 2y ago
R2 is more simply explained as the share of the error variance explained by the model out of the share of the error explained by the best guess, which is, in this case 0.5. Guessing 0.5 will have you wrong wrong by 0.5 100% of the time. SST

I don’t understand why these people are continuing to try to play tennis professionally when the odds of them making something resembling a living wage seems so grim. Like, after a few years of trying it’s got to be obvious. The author here
