functions:

DataLib datalib = new datalib();
//cov
datalib.cov(xList:array1 ,yList:array2);
// this function calculates the covariation between two lists of we enter to parameters


//cor
datalib.cor(xList:array1 ,yList:array2);
//this function calculates the correlation between two lists of we enter to parameters


datalib.populationStandardDeviation(values:array);
//this function calculates the population Standard Deviation a list of we enter to parameters


datalib.sampleStandardDeviation(values:array);
//this function calculates the sample Standard Deviation a list of we enter to parameters


datalib.regressionAnalysis(xList:array1,yList:array2,estimate:estimate);
/*
This function creates the regression equation according to the lists you enter, and based on that equation, it creates an estimated value with the estimated value you give, returns as a list;
index 0 : a value
index 1 : b value
index 2 : estimate result
*/

datalib.arithmaticMean(values:list);
//this function calculates the arithmatic mean a list of we enter to parameter

dataLib.geometricMean(values:list);
//this function calculates the geometric mean a list of we enter to parameter

datalib.harmonicMean(values:list);
//this function calculates the harmonic mean a list of we enter to parameter
