Introduction to Ordinal Regression

[@cypherecon5989]

Best video on this topic. In my lecture it was just cryptic.

[@施沁懷-x7g]

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.

[@devonrd]

Thank you so much for this video. This saved me!

[@ellieaa7256]

Thanks very muuuuuuuch. I wish I had found this video sooner.

[@jordia.2970]

Nice work, thanks!

[@hannahshussain6485]

thank you for this helpful video Dr Gregg

[@lisachen35]

this is an excellent video!! khan academy level quality :) explained a difficult concept in a way that was easy for me to understand and visualize

[@temesgentewolde5767]

This is an amazing tutorial. Thank you very much!

[@kristiapamungkas697]

Amazing introduction and example! Thanks a lot!

[@VictorOrdu]

It was very useful. Thank you!

[@yiwenchen214]

Amazing walk through!!!!! Thank you so much

[@SantamChakraborty]

Excellent video . Thank you.

[@lingyuli9509]

Love it, you solved a lot of mysteries in my head. :)

[@rohitsaigaonkar6869]

THANK YOU SO MUCH!!!! IT WAS REALLY HELPFUL :)

[@caseyj1144]

This was an amazing video

[@rahulraoniar6069]

Wonderful explanation 🥰

[@chilotkassa2655]

Really very interesting lecture

[@zwelithinitunyiswa8166]

This is great. Thank you.

[@PeloquinDavid]

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...

[@matanbendak7027]

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!

[@muniraelhudairi4224]

Thank you very much.

[@alfredkik3675]

Wonderful, love it!

[@sudarshanrbhat7686]

great tutorial. loved it!

[@jakobfriedrich8588]

great video, I think you meant stacked bar chart and not stacked pie chart?

[@Abouelela1]

Simply Amazing!

[@MegaSesamStrasse]

Thanks for this easy but informativ tutorial! It would be nice if you can do a tutorial on hierarchical ordinal regression! & is there a heuristic on how much categories there sould be at maximum?

[@MIJNYT]

How do I know which one (probit or logit) fits my data better?

[@gabrielkamkar2110]

In the Probit Regression, how did you get the specific values for the tau cuts?

[@varunpatwardhan1780]

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!

[@DrGreggHarbaugh]

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.

[@WillIsGoodAtStatistics]

Thanks for the lesson! Is it possible to provide the dataset you have used here?

[@TURALOWEN]

Thank you.

[@LilyWong64]

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()?

[@NMASchubert]

Thanks for the great explanation! When I tried to calculate an odds ratio I only got one value. I have trouble interpreting this value. Do you have any advice on that?

[@filippogambarota2387]

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?

[@አሐዱዘግዮን]

dear can you help me i work my study contain likert scale for both dependent and independent variables then how can i analysis using ordinary regression analysis was it possible to transform thier response into other means or sum then use ORA

[@scottsmall1336]

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?

[@jonathondreyer8644]

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.

[@danielmamaghani]

Thanks

[@anindadatta164]

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

[@bloxyseaashley]

great explanation, but the pace is just a little too brisk.

[@JaneDoe-ck4qs]

Um, that's what pause button is for

[@danielpratson4454]

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?
