2014) heuristic over a range of bimodal distributions as well as bell-shaped and positively skewed distributions
In this paper we focus on one of the most common characteristics, a skewed distribution
With a total sample size of 30 and slightly skewed distributions
, KR is robust when sphericity is assumed, but tends to be liberal when sphericity cannot be assumed, especially when the group sizes are not equal.
Statistical properties of winsorized mean for skewed distributions
Rather than obtain highly skewed distributions
, we get two approximately symmetric distributions that appear like the normal distributions.
To assess the effects of variation in abundance of genotypes, we simulated two genotype frequency distributions: (1) skewed distribution
, where individual were exponentially distributed among genotypes, and (2) even distribution, where there were equal numbers of individuals for all genotypes.
However, the skewed distributions
, had substantial non-zero values for both scores and ranks, although the values for ranks were consistently less.
The chi-square distributions were used to approximate skewed distributions
where the chi-square distribution with 6 degrees of freedom is less skewed than the one with 5 degrees of freedom.
There is no doubt that this book offers a worthwhile experience to its readers, especially for people (academics and practitioners) who are confronting the measurement and management of asymmetric uncertainty and downside risk, or skewed distributions
5) This is a striking observation to support the famous 80-20 principle that has been observed in many other skewed distributions
such as firm size, city size and even repetition of words in literature.
Class discussion about graphic and numeric descriptive statistical analysis included observing the relationship of computed means and standard deviations to the shapes of corresponding histograms and identifying approximately normal and skewed distributions
A statistical article discussing several options for RCVs in skewed distributions
is in preparation.
