specifically the argument of the brown jew who helped the old rabbi, which he didn't explain well but from what I got is this
>if all the atoms were created from the start of the universe on the big bang, how can scientists measure the age of rocks whose atoms are exactly the same which were compressed in the year 0 of the universe using chemicals whose atoms were also there in the age 0?

but his about you /sci/? would you be able to walk to any person and keep debating to death about evolution, or would you be btfo like the canadi*n atheist interviewer was?

also

confidence intervals in multiple regression

No.14256177 ViewReplyOriginalReport
can anyone help me with an irl problem I have?
to do with confidence intervals
I need to calculate confidence intervals from a multiple regression predicted values
ideally using python
basically I ran a multiple regression, and obtained betas for the several ivs, then I am plotting the predictions for one of the variables from 0 to 1000, and all other variables held constant
I get a nice smooth line, but need to plot confidence intervals on it

Google says ols stats models has something like prediction intervals and also confidence intervals

when I plot them, they're very wide, so I think I'm doing it wrong.

I'm using python and getting my coefficients through statsmodels

I generate a linearly spaced array for my variable of interest (dose) from 0 to 1000, then hold the other variables constant and plot the predicted serum concentration as the dose changes.

Also there are confidence intervals reported for the independent variables coefficients.... do these matter in for the confidence interval of the predicted values?

thanks
