Predicting shares for the racer segment
Let's predict shares for a different sportscar segment. I've preloaded the m5 model and the predict_mnl() function I showed you in the video. In the sample code, you will also see my code for creating the prod data frame. Your task is to modify my code to predict shares for the "racer" segment.

Anleitung zur Übung
- Modify my code for creating the
proddata frame so thesegmentvariable is"racer"for both products. Remember that user variables likesegmentshould be the same for all the products inprod. - Predict shares for the products in
produsing them5model. You can use mypredict_mnl()function to do this. Make sure the output indicates that thesegmentis"racer"for both products.

# modify the code below so that the segement is set to "racer" for both alternatives
price <- c(35, 30)
seat <- factor(c(2, 2), levels=c(2,4,5))
trans <- factor(c("manual", "auto"), levels=c("auto", "manual"))
convert <- factor(c("no", "no"), levels=c("no", "yes"))
segment <- factor(c("basic", "basic"), levels=c("basic", "fun", "racer"))
prod <- data.frame(seat, trans, convert, price, segment)
# predict shares for the "racer" segment
