Here^ "PgC^ is the probability density of ^ « It can be shovn (Lee, I96O, 



p. 192) that: 



Equation (A- 5^) may be written: 



R,{x) = ,^^ . ^ j (^=56) 



where;, for - A<x <.Aj 



The absolute value of the slope ^^is used, since in (A- 56) the probability 

 distributions must be positive. 



The complete expression for pv(^K)is given by: 



The term f^60 is, generally^ a function of tj thus, according to the definition 

 in chapter III, it is nonstationary, PofC'^ — f^-.n^i ) may be taken as a rectan^ 

 gular density function (i.e.^. constant probability over a specified interval) 

 and defined as : 



This makes fL^Jifj independent of t^ (i^e., become stationary), and reduces it to: 



A"=ll
