Y's values Y's. Your task is Objective: In this exam, what you are provided are the observed 200 realizations of the for some given pairs (X1, X2)'s thatcan be used to approximatethe distributions of to estimate or approximate the values of (X1, X2)= E(Y(X1, X2)) and V(X1, X2) = Var(Y(X1, X2)) for those given pairs (X1, X2) in the testing dataset. Training data set: In order to help you to develop a reasonable estimation of the mean and variance of Y = Y(X1, X2) as deterministicfunctionsof and X2, we provide a training data set that is generated as follows. We first choose the uniform design points when 0
