 We can compare the estimation performance of the LASSO and SCAD by printing their estimates side by side with the true non-zero parameters values:
 ```@example sim
-[β[1:11] out[1:11] out_las[1:11]]
+[β[1:10] out[1:10] out_las[1:10]]
 ```
-The first entry is the intercept, and the next ten correspond to the non-zero effect.
