Testing and plotting interaction effects: Multiple regression in Stata (updated 2/3/20)

This video demonstrates how to perform moderated multiple regression using Stata involving continuous and binary predictor variables. I demonstrate how to perform basic analyses as well as to probe interaction effects (using the 'margins' and 'marginsplot' commands).

You just saved my thesis Mike, thanks a lot!

[@ranzerkoenig]

thank you for the explanation and providing the code in the text file :)

Hi, you are an excellent teacher. Thank you for generously sharing your training materials with us as well. Your shared files helped me to understand much better. This was the first video I saw of you and I want to continue.

Incredibly useful for my final year dissertation. Thanks Mike

[@mikecrowson2462]

I'm glad it was helpful, Dan. Good luck on completing your dissertation!

It is a very helpful video, Mike. Thank you.

I've been watching several of your vids, very informative, thank you.

Thanks for visiting, Daidi! Best wishes!

@@mikecrowson2462 Can you do one on complex survey analysis, such as analyzing data from a Demographic and Health Survey.

Hi Mike. This is so informative thank you so much. May i kindly ask how you would go about a multiple regression model with multiple interactions. Do you do them individually or there is a way to run the commands with more than 1 interaction at a go? eg, including c.grit_c#c.neglifevts_c and c.grit_c#c.lifesat_c at the same time

The link can't be opened, Mike

The links are not working please

It seems that the link for the data is invalid

[@skateworld2000]

Hi Mike, great video. Can I also use this with pooled OLS regression? I am using panel data

[@danielawilson1048]

I have a question about the interpretation of the interaction based on the marginsplot of the interaction effect? How can we do that? Or what is the right way to do this

[@katherinepicho3679]

Hi Mike- what if I have 2 categorical variables with 2 levels each; 2 focal predictors (i.e. gender, treat) and a moderator (yes/no). Would the code simply involve adding the second focal predictor ?

[@odaamargaa1150]

Hello, Mike your best teacher! I kindly request you if you can do Propensity score matching using SPSS and STATA

[@MohammadAlasadis]

Hey Mike, I'm using xtmelogit for the multiple regression would this work with it as well. Thanks

What a non sense for beginners you did teach how to enter data at least you could enter at each new topic reply must
