A random variable Y has a beta distribution of the second

Chapter 6, Problem 105SE

(choose chapter or problem)

A random variable Y has a beta distribution of the second kind, if, for

\(\alpha>0 \text { and } \beta>0\), its density is

\(f_{Y}(y)=\left\{\begin{array}{ll}  \frac{y^{\alpha-1}}{B(\alpha, \beta)(1+y)^{\alpha+\beta}}, & y>0 \\

0, & \text { elsewhere }  \end{array}\right.\)

Derive the density function of \(U=1 /(1+Y)\)

\alpha >0 and \beta  > 0

fY(y)= {y ^ \alpha-1B(\alpha,\beta )(1+y)^\alpha+\beta,  y > 0, 0,  elsewhere        

U=1/(1+Y)
