Point estimates
A point estimate of a parameter is a single number that can be regarded as a sensible
value for . A point estimate is obtained by selecting a suitable statistic and computing its
value from the given sample data. The selected statistic is

Method of Moments:
The basic idea of this method is to equate certain sample characteristics, such as the
mean, to the corresponding population expected values. Then solving these equations
for unknown parameter values yields the estimators.
