WebbBut in real modeling case, MSE could be described as the addition of model variance, model bias, and irreducible uncertainty (see Bias–variance tradeoff).According to the relationship, the MSE of the estimators could be simply used for the efficiency comparison, which includes the information of estimator variance and bias. This is called MSE criterion.

You could just use different units for what you're measuring and make the standard deviation be numerically whatever you want... the value of one is not a meaningful reference. The variance is just the square of the standard deviation. Webb11 apr. 2014 · 4. Sigma is the variance (i.e. standard deviation squared). If you increase standard deviation in normal distribution, the distribution will be more spread out, and the peak will be less spiky. Similarly in gaussian smoothing, which is a low pass filter, it makes everything blurry, by de-emphasising sharp gradient changes in the image, thus if ...
