StatsPowerPDF

StatsPowerPDF (x, b, c)

The StatsPowerPDF function returns the Power Function probability distribution function

$$\displaystyle f(x, b, c)=\frac{|c|}{x}\left(\frac{\mathrm{x}}{b}\right)^{c},$$

where b is a scale parameter and c is a shape parameter.

For b,c > 0, x is drawn from b >= x >= 0.

For b>0, c<0, x is drawn from x>b.

For b<0, c>0, x is drawn from -b <= x <= 0.

For b<0, c<0, x is drawn from x<-b.

Note that for -1<c<0 the average diverges and the magnitude of a mean calculated from N samples will increase indefinitely with N.
