Let xn be an i. i.d. sample from a rayleigh distribution with parameter θ > 0: f (x|θ ) = x θ 2 e−x2/(2θ 2) , x ≥ 0 (this is an alternative parametrization of that of example a in section 3.6.2.) a. find the method of moments estimate of θ.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
