Webthe MLE and MRR methods as the difference between the estimate and the true value for the parameter. Then we store the median bias from these 1000 values and repeat the process 100 times at the second step of the simulation. The squared median bias is the first component of the pseudo-MSE measure. Webthe MLE is p^= :55 Note: 1. The MLE for pturned out to be exactly the fraction of heads we saw in our data. 2. The MLE is computed from the data. That is, it is a statistic. 3.
