WebIn fact, the notion of skew information is very similar to the well-known notion of Fisher information originated from statistical inference [5], [6]. Recall that the Fisher information of a parameterized family of probability densities fp : 2Rg on Ris de ned as I F(p )= Z R @ @ p1=2 (x) 2 (1) dx = 1 4 Z R @ @ logp (x) 2 (2) p (x)dx: WebMar 8, 2024 · Skewness is a measure of asymmetry or distortion of symmetric distribution. It measures the deviation of the given distribution of a random variable from a symmetric distribution, such as normal distribution. A normal distribution is without any skewness, as it is symmetrical on both sides. Hence, a curve is regarded as skewed if it is shifted ...
