While you are doing a different kind of regularization you will still use the same penalty argument. I have picked a different range for the values of penalty since I know it will be a good range. You would in practice have to cast a wide net at first and then narrow on the range of interest. Use the output penalty$\_$grid. Use $50$ levels and set a range going from $[-2,2].$ Use the function grid$\_$regular.

# $*$your code here$*$

$$

#penalty$\_$grid $<-$

penalty$\_$object $<-$ penalty$($range $=$ c$(-2,2))$

$$

penalty$\_$grid $<-$ grid$\_$regular$($

penalty$\_$object,

levels $=50$
