- *
- *	Beta distribution
- *
- *
- *
- * SYNOPSIS:
- *
- * long double a, b, x, y, btdtrl();
- *
- * y = btdtrl( a, b, x );
- *
- *
- *
- * DESCRIPTION:
- *
- * Returns the area from zero to x under the beta density
- * function:
- *
- *
- *                          x
- *            -             -
- *           | (a+b)       | |  a-1      b-1
- * P(x)  =  ----------     |   t    (1-t)    dt
- *           -     -     | |
- *          | (a) | (b)   -
- *                         0
- *
- *
- * The mean value of this distribution is a/(a+b).  The variance
- * is ab/[(a+b)^2 (a+b+1)].
- *
- * This function is identical to the incomplete beta integral
- * function, incbetl(a, b, x).
- *
- * The complemented function is
- *
- * 1 - P(1-x)  =  incbetl( b, a, x );
- *
- *
- * ACCURACY:
- *
- * See incbetl.c.
