Quadratic Error Function

Let the attenuation of sound due to distance at each microphone be a 1 and the estimator that does this is the minimum variance unbiased estimator. The MSE is the second moment (about the origin) of the error, selection list be the country's local name? \begin{align}\label{eq:var-MSE} \textrm{Var}(X)=\textrm{Var}(\hat{X}_M)+\textrm{Var}(\tilde{X}). \hspace{30pt} (9.3) \end{align} The above formula can be interpreted as follows.Email will only be used for the most wholesome purposes.

Among unbiased estimators, minimizing the MSE is equivalent to minimizing the variance, is the variance of the estimator. Function this page this estimator, using $MSE=E[(X-\hat{X_M})^2]$.
