hey Dr. Mike Crowson. Could you please explain the order of each variable entry in categorical regression? Since some variables share the same variance, the results ( r squared change) may vary without considering it.
Hi there. It looks like the latter is a misspelling of the former. The 'i' and 'y' on the keyboard are not far apart. My apologies if it was my misspelling. Cheers!
Hi Mike, thank you a lot. I'm conducting a regression analysis as well and it seems like the gender is having a moderator role and because of that I'll have to conduct a hierarchical regression with the gender as a control variable. But the problem I'm facing is that SPSS (i have both versions 25 and 28) won't let me put a string variable in the independent variable list. In this video I see that you've used a string variable in the list and I wanted to ask how can I do the same and do you maybe know why doesn't SPSS allow me that, is it some setting for example? And is it possible that I can change it/enable string variables as predictors? Thank you in advance 🤗
Hi Maria, regarding your question about string variables, there's no way to enter a string variable directly into the regression. You can enter a quantitative variable or binary variables. For this example, I created a binary variable (coded 0=male, 1=female) that was included in the regression. I just named the binary variable genderid. When interpreting the results I interpreted the regression coefficient for genderid in light of the coding system used. Cheers!
Sir, since genderID not significant, do we include that in the regression equation and use it along with other predictor variables to predict the dependent variable?
Hello, yes of course. The only thing I would consider in doing this is to make sure that you have a sound rationale for that modeling strategy. There's nothing inherently right or wrong with you doing this. But it needs to fit with the objectives of your analysis. Cheers!
this explanation was very good and helpful! thank you for helping us not fail our stats assignment
Supplementary PPT is helpful to your lecture-explanation. Thank you for your full package of discussion.
Glad it was helpful!
Thanks for the very clear and thorough explanations!
That's really helpful! Thanks a lot for this video
This video was very informative! Thank you so much for making it!
Dude, you're the best!
Thanks for this great video.
Thank you for visiting Erfan!
Thank you for uploading it!
Very helpful, thank you!
very helpful! Thanks!
This was great! Are you on Kahn academy? Your voice is familiar
thank you

Thank You
Hi Mike. I have a question: what is the difference between hierarchical multiple regression and hyerarchical linear models? Thank you in advanced

Hi Mike and thank you. in meta analysis, do we consider the Beta of the last model?
Hi Shirin, I'll be honest. I don't really do much in the way of meta analysis. Thanks for visiting!
If I have 5 predictors, can I start my model 1 with 3 predictors and then add two more predictors in my model 2?

Dear sir if we have seven predictors how we can analyze it in 3 steps
