Exponential Distribution
Shape:
The exponential distribution is a 2-parameter distribution and covers any specified average and standard deviation. It is represented by a single point with a skewness of 2 and kurtosis of 9 (excess kurtosis of 6) on a skewness-kurtosis plot as shown below:
Density Function:
The density function of the exponential distribution is shown below:
The equation, parameters and bounds of the density function are:
Moments:
The moments of the exponential distribution can be calculated from the parameters as shown below:
Properties:
The exponential distribution is a special case of the both the gamma and Weibull distributions falling at the intersection of these two curves on the skewness-kurtosis plot.
