Question

Let Chi 1, ..., Xn be a random sample from the uniform distribution on the interval [a − b, a + b], a ? R and b > 0. (a) Verify if a and b are location and/or scale parameters. (b) Obtain the maximum likelihood estimator of a and b. (c) Assume now that b = 1 and define (d) Compare Tau 1 and T2 in terms of bias, risk and consistency, specifying choice among them and justifying this choice.

Step 1

- A location parameter shifts the distribution along the x-axis without changing its shape. - A scale parameter stretches or compresses the distribution without changing its location. In this case, a is a location parameter because it shifts the distribution Show more…
