Suppose that we have data y = (y₁, ... ,yn). Each data-point is assumed to be generated by a distribution with the following probability density function: p(y¡ | 4) = 24y¡ exp(−¥y?), y¡ ≥ 0, i = 1,...,n. The unknown parameter is , with > 0. Write down the likelihood for given y. Find an expression for the maximum likelihood estimate (MLE) .
