Great Video :) How would you include dummy factors in a similarly easy to use manner? If we use the housing example, for instance a Tick-Box for "Roof-Terasse" (that if ticked adds a simple summand value)...
why do you put defined values and not variables of the vector of coefficients in the regression? this would allow you an automatic update of the coefficients as the data is updated. good video
Agree with you Maximiliano!! One can extract the parameters that the regression creates and use those in the formula. I guess that is more of a Power Query exerciser and it would extend the video too much.
This may seem like a silly question, but I noticed you have histograms and other useful info at the top of each variable column--as an R user trying to learn BI (and wanting to pull my hair out at every step) I'm wondering how you enable this functionality? is it a plugin? Also, thanks for your helpful video!
when I run the R script I get this error "Error in setwd("~/Documents/R") : cannot change working directory" , can you please help me with this problem? Cheers Jeff.

Greta video and explanations! you master well what you do. Beautiful ❤
Amazing video and thorough explanation! Helped me a lot, thank you.

Any advice on incorporating non numerical explanatory variables? E.g. Country??
I love youuu 😚. Very useful

The Bedrooms values are negative, and your calculation did not reflect that the forecast should be 450L instead of 334K
Can you provide python script as well?
Does anyone who views this Power BI workbook have to have R installed?
You don't need R to view the workbook but you do need R installed to run the script. Power BI will automatically pick up R is installed.
