If I ever teach a class that covers two-way ANOVA, I might. If you run across a video of mine, it's most likely because it's for a specific class I'm teaching.
Well, you would need a y-hat value for each data point in your observed ordered pairs. This means you would need every ordered pair (x,y) (x = explanatory value, y = response value) in your bivariate data set. Also, you need the regression equation evaluated at that ordered pair's x-value. For example, let's say you observe x=10 and y = 15, and your regression equation is y-hat = 1.3x + 2.4 Then letting x = 10 would give y-hat = 1.3(10) + 2.4 = 15.4 If you happened to have your complete bivariate data set in Excel, it would be easy to calculate the y-hat's, as well as anything else you need. Hope this help. In the book I was using for this class, the authors were notorious for saying "using a computer output, we get these values" without ever actually calculating those values. As a theoretical mathematician, this drives me crazy!
Thank you 👍👍👍👍👍🙏🏼
Welcome 👍
Hello,can you plz make it same for two way ANOVA classification for linear Regression

How to find y hat using regression model and without anova table given!?
