Examples

var vec1: Vector;
LowInt,HighInt,p: Vector;
begin
    vec1.Size(1000);
    RandomBinom(35,0.25,vec1);
    // Now extract p-s and its 100*(1-Alpha)
    // confidence intervals.
    BinomFit(vec1,35,p,LowInt,HighInt);
    // vector p holds the p for each element in vec1,
    // vectors LowInt and HighInt hold the lower and upper conf. int. limit
    // for each element in p
end;

Overload 3: procedure BinomFit(const X: TVec; N: Double; const p: TVec; const Low: TVec; const High: TVec; Alpha: Double);

Calculate parameters for binomial distributed values.

#	Name	Description
1	X	Stores data which is assumed to be binomial distributed.
2	N	Defines binomial distribution n parameter.
3	p	Returns binomial distribution p parameter, estimated at each X value.
4	Low
5	High	p (1-Alpha)*100 percent confidence intervals. Each pair of Low and High values defines lower and upper CI for corresponding p value.
6	Alpha	Confidence interval percentage.
