Geometric

 template doublegeometric( int n T* data )
The geometric mean of a sequence  is defined by:


Thus,



and so on. For , 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

 n the size of the population data the actual population data given as an array

Returns

return value the geometric mean of the given population
