Example

The following example generates 100 random logistic distributed values and then uses LogisticFit routine to extract used m and b parameters:

Uses StatRandom, Statistics, MtxExpr;
procecure Example;
  var Data :Vector;
  m,b: double;
begin
  Data.Size(100);
  RandomLogistic(3,0.2,Data);
  LogisticFit(Data,m,b);
  // m approx 3.0
  // b approx 0.2
end;

#include "StatRandom.hpp"
#include "MtxExpr.hpp"
#include "Statistics.hpp"
void __fastcall Example();
{
  sVector Data;
  Data.Size(100,false);
  RandomLogistic(3,0.2,Data);
  double m, b;
  LogisticFit(Data,m,b);
  // m approx 3.0
  // b approx 0.2
}
