Hi everyone,
I have a problem with maximum-likelihood-estimation in the following
situation:
Assume a functional relation y = f(x) (the specific form of f should be
irrelevant). For my observations I assume (for simplicity) white noise,
such that hat(y_i) = f(x_i) + epsilon_i, with the epsilon_i
Hi all,
I am trying to find out how a certain functionality is implemented in R
respectively what a certain found does exactly.
Specifically I am interested in multivariate kernel density estimation.
I found the ks package and its kde function. Usually, my preferred
way to look under the hood of
Thank you David and Thierry, your answers helped a lot!
Kind regards,

Dear all,
I have a problem when trying to present the results of several
regression. Say I have run several regressions on a dataset and saved
the different results (as in the mini example below). I then want to
loop over the regression results in
the details.
Thanks a lot anyways for solving my coding problem!

To be honest, I'm stumped and don't quite know what the problem is...
