Geometric

 
template<class T> doublegeometricintn
T*data )
The geometric mean of a sequence x_i is defined by:

Thus,

and so on. For N=2, the geometric mean is related to the arithmetic mean and harmonic mean by where:
  • A = arithmetic mean and
  • H = harmonic mean]

Example 1

#include <codecogs/statistics/moments/geometric.h>
#include <iostream>
#include<math.h>
int main() 
{
  int x[5] = {4 , 6 , 1 , 3 , 7};
  double geom = Stats::Moments::geometric(5, x);
  std::cout << "The population mean is: " << geom << std::endl;
  return 0;
}
Output:
The population mean is: 3.47125

Parameters

nthe size of the population
datathe actual population data given as an array

Returns

return value the geometric mean of the given population
