Moments of a Distribution
The first four moments of a distribution are:
Average - measures the location of the distribution.
Standard Deviation - measures the width of the distribution. Referred to as the scale parameter.
Skewness - measures the symmetry of the distribution. Referred to as the first shape parameter.
Kurtosis - measure of the heaviness of the tails and peakedness of the center of a distribution. Referred to as the second shape parameter.
Different distributions with the same moments will have similar density functions and behave nearly identical.
