Chapter 4 Problem 4.4
I have the following questions. I have a few more on using Legendre polynomials but I will read 4.3 first before asking
a) what does selecting independently with P(x) mean? In earlier homework, we selected the points at random from [1,1] which was clear to me  I used a random function with min = 1 and max = +1 but I am not clear what to do with P(x) b) is clear since it is f(). Should we generate random numbers for each ? If so, what are the min and max values for the random numbers? Thank you!

Re: Chapter 4 Problem 4.4
Thank you for the reply! How can I generate Gaussian random numbers with mean 0 and variance 1? I am programming in C#.

Re: Chapter 4 Problem 4.4
Hello,
just another question about this problem: What I supposed to do to select the coefficients ai, in order to respect the restriction of Ea,x [f^2] = 1 ? Best regards, Kleber

Re: Chapter 4 Problem 4.4
Quick question: what does the "LAMi" at the beginning of the problem mean?

Spurious typo that snuck in, sorry.

Re: Chapter 4 Problem 4.4
Rescale all the weights by a constant factor so that Ea,x [f^2] = 1.
