The ranges of different variables are different, so we need to implement different normalization techniques. The codes to run normalization are as follows:

mydata predict$($preProcess$($mydataImp$,$ method range"$)),$ mydataImp$)$

Question $10$: From the above code, which normalization method is used?

None of the above

min$-$max normalization

z$-$score normalization

Box$-$cox
