    I've learned more in this hour than in a four-months course

      Alize Leal why is this so painfully true
      I am sitting here an hour before the online exam due to covid and it’s just mind blowing of how scared I was all semester cause I don’t understand anything but it’s actually the prof 😂😌

    This is the best explanation of exponential family i have ever come across.

    @29:10 an Army of CDF's that map to 0 to 1 and are invertible. Such simplicity. Love it

    Excellent lecture, horrible recording. Hardly hear anything with max volume and why the camera has to shoot at the prof speaking rather than staying on the slides? It is very distracting and hard to follow.

      You can also use subs to get the rest, especially if your mother tongue is not English

    I think there's some confusing notations at 27:10, which should be :
    The response variable is binary so there is no choic: Y|X is Bernoullli with expected value μ(Y|X) ∈(0,1)
    We can't write μ(Y|X) = X^T * β.

  • @nabilakdim2767

    I think that choosing the distrib on Y is mostly done based on MaxEnt principle, not arbitrarily as said around 19:45.

    Good course. Just the recording crew needs to realize that in a math class you're not supposed to be staring at the instructor. Instead you look at the board and the slides more

    Is that really the reason? Why not then define eta(theta,phi) = theta/phi ?
    I thought the reason it may not turn into the exponential family may have to do with the fact that c(y,theta) may be not separable.

      It seems he clarifies it later. I just had to be a bit more patient!

    Thanks for your presentation. Please in the case we use ordinal logit , should we report pearson correlation and omnibus test value? if it is the case, how to interpret them (for exemple, under or above p value, what it is the meaning). Also shoud we consider the sig level from the table 'Test of model effect' or 'Parameter Estimates' table to say that a relationship between the predictor and outcome variable is significant. I am really looking for ways to interpret, your answer will really help me. thanks.

    It is mentioned that "phi is known positive value" (Lecture 23: 16.28 min). I am wondering, if exponential dist. comes under canonical exponential family (or not), where theta = lambda, b(theta) = ln(theta) and phi = -1?

    i wish GLM is taught this way. Remember how he started, simplying the context of GLM!!??

  • @mantistoboggan537
    @mantistoboggan537 5 ปีที่แล้ว +2

    Sorry I'm having trouble keeping up, but for the Poisson example, where does that expression for mu(x) come from?
    This is terrific by the way- thank you MIT for helping me stay even a little afloat in one of my classes.

    • @tempvariable

      Can you tell us which example for Poisson ? The disease example?

      @betrayalact2610 4 ปีที่แล้ว +1

      It's just low, I don't think that actually quality is that bad. Also, this was delivered as a live lecture which means sometimes not everything will work perfectly.
