I think your videos are not being appreciated enough, millions of people could apply this tools in many aspects and probably don't know. It was only in one of your videos that I discovered how to perform RSM in R after a long time of search. Thank you so much, you made a great impact to me.
Great..... Doctor your videos need to be frequent and appreciated ❤❤❤ Lots of love for such professors who keep their time to teach globally without any greed for money 🙏🙏
Hello. I'm constructing a 3 variable model and when i use persp, instead of x1~x2 i use x1~x2~x3. I was expecting to have 3 plots showing each interactions but I have 3 plots with interactions of x1 and x3 and x2 and x3 twice. Do you happen to know if I have to add something in the code to add x1~x2 interaction? Thank you

It should work, but if it doesn't, you can build them in pairs (~x1+x2, ~x1+x3 and ~x2+x3)
Can this be used for single replication? 😢
Yes, if you have enough degrees of freedom.
