Then we have Pr [ Y = 0] = Pr [ X ≤ 0] = F X ( 0). Furthermore, for y > 0, Pr [ Y ≤ y] = Pr [ max ( X, 0) ≤ y] = Pr [ X ≤ y] = F X ( y), because if X < 0, then it is also the case that X < y since y > 0; and if X > 0, then max ( X, 0) = X. darcy houckWebLet X be a continuous random variable with cumulative distribution function { F(x) = (a) Find the density function of X.
