Description

The list of methods to do Geometric Mean are organized into topic(s).

Method

doublegeometricMean(double a, double b)
geometric Mean 
return Math.pow(a * b, 0.5);
doublegeometricMean(double... values)
geometric Mean 
return Math.pow(product(values), 1. / values.length);
doublegeometricMean(double[] nums)
Return the geometric mean of an array of numbers. 
double prod = 1.0;
for (double num : nums) {
    prod *= num;
return Math.pow(prod, 1.0 / (double) nums.length);
doublegeometricMean(double[] values)
Calculates the geometric mean The geometric mean is the product of all values in the array to the Nth root, where N is the total number of values in the array. 
double geometricMean;
int size = values.length;
double[] logValues = new double[size];
for (int i = 0; i < size; i++) {
    logValues[i] = Math.log(values[i]);
geometricMean = geometricMeanFromLog(logValues);
return geometricMean;
...
doublegeometricMean(final double[] values)
Returns the geometric mean of the entries in the input array. 
return (geometricMean(values, null));
floatgeometricMean(float[] xs)
geometric Mean 
if (xs == null || xs.length == 0)
    throw new IllegalArgumentException("Input to mean() is an empty array");
float prod = 1.0f;
for (int i = 0; i < xs.length; ++i)
    prod *= xs[i];
return (float) Math.pow((double) prod, 1.0 / xs.length);
doublegeometricMeanFromLog(double[] logValues)
Calculates the geometric mean of log values. 
double logArithmeticMean = arithmeticMean(logValues);
double geometricMean = Math.exp(logArithmeticMean);
return geometricMean;
