ThenThe statistic \(T(\mathbf{X})=(\frac{f_1(\mathbf{X})}{f_0(\mathbf{X})},\frac{f_2(\mathbf{X})}{f_0(\mathbf{X})},\cdots,\frac{f_k(\mathbf{X})}{f_0(\mathbf{X})})\) is minimal sufficient for the family \(\{f_0(\mathbf{x}),\cdots,f_k(\mathbf{x})\}\). \(X_{(1)}\) is also complete as we desire.0.
How To Create What Is A Random Assignment In Statistics
For example, let N be a random variable taking values \(1,2,\cdots\) with known probabilities \(p_1,p_2,\cdots\), where \(\sum_{i=1}^{\infty}p_i=1\).5
