Rectified Gaussian	$p^{\text{RG}}(h;\gamma )=\sqrt{\frac{2}{\pi \gamma }}\text{exp}\left(-\frac{h^2}{2\gamma }\right)u(h)$
Exponential	$p^{ Exp }(h;\gamma )=\gamma \text{exp\hspace{0.17em}}(-\gamma h)u(h)$
Inverse Gamma	$p^{\text{lGa}}(h;a,b)=\frac{b^a}{\Gamma (a)}{h}^{-a-1}\text{exp\hspace{0.17em}}\left(-\frac{b}{h}\right)u(h)$
Gamma	$p^{\text{Ga}}(h;a,b)=\frac{1}{\Gamma (a)b^a}{h}^{a-1}\text{exp\hspace{0.17em}}(-hb)u(h)$
Rectified Student’s-t	$p^{\text{RST}}(h;\tau )=\frac{2\Gamma \left(\frac{\tau +1}{2}\right)}{\sqrt{\tau \pi }\Gamma \left(\frac{\tau }{2}\right)}{\left(1+\frac{h^2}{\tau }\right)}^{-\frac{(\tau +1)}{2}}u(h)$
Rectified Generalized Double Pareto	$p^{\text{RGDP}}(h;a,b,\tau )=2\eta {\left(1+\frac{h^b}{\tau a^b}\right)}^{-\left(\tau +\frac{1}{b}\right)}u(h)$
