| Hi Tianyi, Honestly don't try to understand it, it seems to be a mistake. It took me a while to understand what was going on. I'm a mathematician in discrete mathematics, so I have limited knowledge of complex analysis. When I wrote that lesson, I... |
| Yes, it works. Thank you, Gianluca. |
| For Exercise 4.3.4 I am getting the same output with I use standard deviation or r-squared both are equivalent to the "Expected Output", but neither result allow me to get a Correct answer from the auto-grader. Since this course was originally... |

| Hello Peter, Indeed, as Dave pointed out, you're basically abusing of the [properties of expectation][1]. Notice f(E(x)) is equal to E(f(x)) if f(x) is a linear function. For non-linear functions, f(E(x)) is not equal to E(f(x)). Norm is not a... |
| Unfortunately, there is no way to go back to R 4.1.1. Many common R packages are not longer compatible with this „old“ R version. |
| Giulio, Thank you. Your solution works well. Have a nice weekend. |
