We have access K samples in order to compute our estimation. Select one or more statement(s) from the options below that are correct about model free or model based approaches? A) Model Free Approach first tries to estimates the probability distribution before estimating the expectation B) Model Based Approach first tries to estimates the probability distribution before estimating the expectation C) Model Based Approach estimate would be given by ΣK i=1 f(Xi)/K D) Model Free Approach estimate would be given by ΣK i=1 f(Xi)/K
