binomial_fit()

double binomial_fit	(	vector< double > &	distrib,
		int	n,
		int	nfit,
		vector< double > &	coeff
	)

Fits a distribution to one or more binomial distributions.

Author

Parameters

&distrib	distribution.
n	number of cases (number of values in distribution).
nfit	number of binomial curves to fit.
&coeff	fitted coefficients (weights and probabilities).

Returns

double residual.

The binomial curve(s) is(are) fit using the downhill simplex method.

Bnpk()

double Bnpk	(	int	n,
		double	p,
		int	k,
		double	w
	)

Calculates the probability of k occurrences in n cases.

Author

Parameters

n	number of cases.
p	probability of one occurrence [0-1].
k	occurrences (<=n).
w	weight [0-1].

Returns

double weighted probability.
