    <P>
 
58
    Calculates any one parameter of the Non-central F
 
59
    distribution given values for the others.</P>
 
60
    <P>
 
61
    Formula  26.6.20   of   Abramowitz   and   Stegun,  Handbook  of
 
62
    Mathematical  Functions (1966) is used to compute the cumulative
 
63
    distribution function.</P>
 
64
    <P>
 
65
    Computation of other parameters involve a seach for a value that
 
66
    produces  the desired  value  of P.   The search relies  on  the
 
67
    monotinicity of P with the other parameter.</P>
 
68
    <P>
 
69
    The computation time  required for this  routine is proportional
 
70
    to the noncentrality  parameter  (PNONC).  Very large  values of
 
71
    this parameter can consume immense  computer resources.  This is
 
72
    why the search range is bounded by 10,000.</P>
 
73
    <P>
 
74
    The  value  of the  cumulative  noncentral F distribution is not
 
75
    necessarily monotone in either degrees  of freedom.  There  thus
 
76
    may be two values that provide a given  CDF value.  This routine
 
77
    assumes monotonicity  and will find  an arbitrary one of the two
 
78
    values.</P>
