Examples

Uses MtxExpr, Math387, Statistics;
procedure Example;
var vec1: Vector;
resp: double;
CIp: TTwoElmReal;
begin
    // first, generate 1000 randomly geometr. distributed
    // numbers with parameter p=0.713
    vec1.Size(1000);
    RandomGeometric(0.713,vec1);
    // Now, extract the p and its 100*(1-0.05) = 95%
    // confidence interval
    GeometricFit(vec1,resp,CIp);
end;

Overload 2: procedure GeometricFit(const X: TVec; out P: Double; var PCI: TDoubleArray; Alpha: Double);

#	Name	Description
1	X	Stores data which is assumed to be geometricaly distributed.
2	P	Returns geometric distribution parameter estimator.
3	PCI	P (1-Alpha)*100 percent confidence interval.
4	Alpha	Confidence interval percentage.

Result: stored in self (calling object)
