WebJul 15, 2016 · The PERT distribution (also called the beta-PERT or three-point estimation technique) is a smooth version of the uniform distribution or triangular distribution. It is defined by: The minimum: the smallest value in a set. Can be any real number. The maximum: the largest value in a set. Can be any real number. WebIf a = b, then the pdf of beta(a;b) is symmetric about 1 2. For any r >0, if X ˘beta(a;b), then E(Xr) = ( a+b) ( a)( b) Z1 0 xr+a 1(1 x)b 1dx = ( a+b)( r +a) ( a)( r +a+b) In particular, E(X) = a a+b; E(X2) = a(a+1) (a+b)(a+b +1) Then Var(X) = a(a+1) (a+b)(a+b +1) a2 (a+b)2 = ab (a+b)2(a+b +1) The family of beta(a;b) distributions is an ...
