We present the sampling distributions for the coefficient of skewness, kurtosis, and a joint test of normality for time series observations. We show that when the data are serially correlated, ...

Skewness measures the symmetry of your data. It can indicate whether or not your data adheres to a normal distribution. It’s okay for your data to have skewness, it can indicate outliers in your data ...

The purpose of the Institute of Mathematical Statistics (IMS) is to foster the development and dissemination of the theory and applications of statistics and probability. The Institute was formed at a ...

What is the difference between positive skew versus negative skew? Skewness is the measurement of a a coefficient that has the ability to be positive, negative or neutral (zero). The coefficient of ...

As is well known, the normal distribution is a key tool in probability and statistics. It can be described as a distribution that obeys a universal rule derived from one of the most important theorems ...
