Here we propose and discuss the GC skew index (GCSI) for the quantifi cation of genomic compositional skew, which combines a normalized measure of fast Fourier transform to capture the shape of the skew graph and Euclidean distance between the two vertices in a cumulative skew graph to represent the degree of skew. This would be a positive skew, with the data distribution of the numeric vector in your data frame or dataset leans towards the right, or values in the upper quantile. A normal distribution does not have a positive skew or negative skew, but rather the probability distribution is a symmetrical bell curve.

2016-02-01 · One shortcut for understanding how changes in the Skew Index translate to risk is this: each five-point move in the Skew Index adds or subtracts about 1.3 or 1.4 percentage points to the risk of a two-standard deviation move. A five-point move adds or subtracts approximately 0.3 percentage points to a three-standard deviation move.

Variance: Variance. Sample Number: In the older notion of nonparametric skew, defined as (−) /, where is the mean, is the median, and is the standard deviation, the skewness is defined in terms of this relationship: positive/right nonparametric skew means the mean is greater than (to the right of) the median, while negative/left nonparametric skew means the mean is less than (to the left of) the median.
