Abstract AR
This article considers a shrunken estimator of Al-Hermyari and Al-Goburi (١) to estimate the mean (زو of a Donnai distribution N(0.
a2) with known variance (a2), when a guess value (0°) is available about the mean (9) as an initial estimate.
'Phis estimator is shown to be more efficient than the classical estimators especially when ؛ وs close to 0».
General expressions for bias and MSE of considered estimator are given, W'ith some examples.
Numerical results, comparisons and conclusions are reported.
