A test is proposed for the homogeneity of two samples of bivariate observations, based on the \(L_2\) distance between the empirical characteristic functions of these samples. Two approaches to numerical calculation of the \(L_2\) distance are discussed: the Powell-Sabin quadratic triangular splines interpolation and the picewise quadratic Taylor expansion. Two bootstrap procedures are compared via simulations for the test critical point evaluation.
