We know by convolution that the distribution of Z = X + Y is given by: f ( z) = { z if 0 ≤ z ≤ 1 2 − z if 1 ≤ z ≤ 2
NettetIn general (unless c 1 = c 2) you will have three segments. Try to evaluate f ( z) at a few different values of z to see what the shape of that density is. The tricky part is to … NettetIt is easy to show that if we have n independent normally distributed random variables, then a linear combination fo them ar normally distributed. It is also said that if (x1,x2,..,xn) is multivariate normally distributed, but not nececarrily independent, then any linear combination is also normally distributed.
Nettetwe can see more clearly that the sample mean is a linear combination of the random variables \(X_1, X_2, \ldots, X_n\). That's why the title and subject of this page! That … NettetVariance of linear combinations of correlated random variables. but I don't understand how to prove the generalization to arbitrary linear combinations. Let a i be scalars for i …
