Question: Let f(x, y|1, 2, 3, 4) be the bivariate pdf for the uniform distribution on the rectangle with lower left corner (1, 2) and upper

Let f(x, y|θ1, θ2, θ3, θ4) be the bivariate pdf for the uniform distribution on the rectangle with lower left corner (θ1, θ2) and upper right corner (θ3, θ4) in ℜ2. The parameters satisfy θ1 < θ2 and θ3 < θ4. Let (X1, Y1),..., (Xn, Yn) be a random sample from this pdf. Find a four-dimensional sufficient statistic for (θ1, θ2, θ3, θ4).
