Let µ^ = r(X 1;¢¢¢ ;Xn) = r(X) be an arbitrary estimator of µ. Assume Eµ(µ^) = m(µ), and the variance of µ^is flnite. Let us consider the random variable l0 n(Xjµ) deflned in (4), it was shown in (5) that Eµ[l0 n(Xjµ)] = 0.

WebMay 7, 2024 · We can use the following syntax on a TI-84 calculator to find this percentile: normalcdf(-99, -1.44, 0, 1) Note: We use -99 as the “lower bound” to simulate a value of negative infinity. The percentile that corresponds to a z-score of -1.44 is 0.0749. This means that only 7.49% of values in the normal distribution fall below a z-score of -1.44.
