This is the most helpful video talking about the intuitive concept behind the ordered regression that I can found on KZbin. Thank you so much.

A really great explanation! Thank you! Some minor mistake in writing: at 14:19 you wrote F_Unlikely = exp(-0.82) but you meant 0.44/(1+0.44) instead. Same for F_somewhat Thanks!

Thank you so much! This is extremely helpful. I do have one question - at 14:20 shouldn't the probability equations be F(unlikely) = 0.44/(1+0.44) = 0.306 and F(somewhat) = 3.58/(1+3.58) = 0.782 instead of exp()?

Thanks! this is very helpful! I'm wondering if there is a way to assess the effect of a predictor X on the thresholds (intercepts) estimation. Are the thresholds assumed to be constant and pre-determined?

Good illustration, but I couldn't stop wondering (and being sceptical) - in relation to the probit model - of the statement early on that since we CAN'T observe y* (the latent variable), we can simply ASSUME it has a normal distribution. What on earth is the theoretical justification for this? Presumably a similar assumption is implied by the logistic regression's standard functional form (i.e. a linear relationship between the log of the odds ratio (the dependent variable) and the explanatory variables, though the video is completely silent about what the theoretical justificationbof that implied assumption might be...

Wonderful video, thank you! One question, how would we be able to state the effect of an independent variable on the outcome? For instance, how can I express whether or not public school attendance is significantly associated with an increase likelihood of applying to grad school?
@jonathondreyer86442 жыл бұрын
I believe a p-value of less than 0.05 for the predictor is considered significant. I'm not sure how to get p-values in ordinal regression though in R. There may be a different metric for measuring variable significance in ordinal regression.

Thanks for a helpful video. I'm new to ordinal regression and your's was the first video I've watched. The point where I was lost was the animation of bell curve movement with changes in GPA. How can the bell curve move if the value of boundaries is already defined? I can see how we'll get different Y* value with changes in GPA. However, I can't see how bell curve itself will move around on a likert scale!
@DrGreggHarbaugh3 жыл бұрын
The y* value comes from the equation, and the y* is the location of the center (mean) of the bell curve. So, say x increases, then y* increases, and thus the center of the bell curve increases along the axis. I hope this helps.

How did you calculate the probability values for the ordinal probit regression model? For the instance with the specific student, how did you calculate the probability of them answering "somewhat" as 0.449?

The video could have better explained how to arrive at the regression coefficients and intercept when dependent variables have dummy values.
