question: public PartialCorrelationPdf ( int n , int k ) { this . n = n ; this . k = k ; double gammaRatio = gammaRatio ( n , k ) ; this . constant = ( 1 / Math . pow ( Math . PI , 0.5 ) ) * gammaRatio ; this . outsideExp = ( double ) ( n - k - 2 ) / 2.0 ; }
target:  Constructs a new zero partial correlation distribution function with the given values for n and k.
