    This is what a seekers needs. Short details, straight to point, using examples, behavior of model and others. Thanks.

      I guess im randomly asking but does anyone know a tool to log back into an Instagram account??
      I somehow forgot the login password. I love any assistance you can give me!

      @Otis Aldo i really appreciate your reply. I found the site through google and Im trying it out atm.
      Takes quite some time so I will reply here later when my account password hopefully is recovered.

      @Otis Aldo It worked and I finally got access to my account again. I am so happy:D
      Thank you so much you saved my account :D

    Could you provide a link to the literature where the Akaike criterion is calculated using the formula you cite?

    sir good work, but confusion confounded on your explanation at 11.37/17.19, can you elaborate sir

    Hello
    I was wondering if my statiscal analysis of the residuals or errors, reveals that they are Normalized but lack a Constant Variance, can I still assume that the L can be calculated by SSE/n?

    Great lecture.
    One question: Where do these parsimony metrics have an advantage over 'noise-sensitivity' metrics like the PRESS statistic?
    The standard guide that my work perscribes is the press statistic. I've been going on a crusade of all the perscriped methods that come w/o a justification and comparison of alternatives.

      I use PRESS as well. There is no one metric that is best at all things. I typically compute many metrics when comparing models. When they agree, of course there is no question. When the "best" few models are ranked differently by the different metrics, I tend to use judgment based on my knowledge of the problem (that is, non-statistical criterion).

    Can anyone explain where the 'n' comes from (14:07. second row)?
    It is my understanding that the likelihood inside the log should be maximum likelihood under the assumption of Gaussian distribution.
    Then, the maximum likelihood estimator is equal to the mean square estimator, leading to -2ln(L) = nlog(SSE) -nlog(n) +2p. I am not sure where the extra n comes from

    Can you discuss any numerical examples using these criteria? I am a biomedical student and I want to compare two risk prediction models. From your video, it is clear that AIC or BIC can be used to select a good model. But, Can you share any numerical example related to this video?

    Hello Sir, can I use Aic or Bic for robust Standard errors (NewyWest) ? How can I applied in R? Tranks 😉

    I prefer Bozdogan IC = -2LL+K(1+ln(N)) for strogest penalty term and most "stretchig" among c- models!
