hi comparing statistics between matlab , apache functions. here apache functions tested in java. same set of data, different results double array (double[] ) follow: --------------------------------------- matlab vs apache --------------------------------------- max = 0.5451 vs 0.5450980392156862 min = 0.4941 vs 0.49411764705882355 var = 5.4154e-05 vs 5.415357603461868e-5 std = 0.0074 vs 0.007358911334879547 mean = 0.5206 vs 0.5205525290240967 kurtosis = 3.3442 vs 0.35227427833465486 skewness = 0.2643 vs 0.26466432504210746 i checked , rechecked data, each value matlabs same used in java. here can see statistics identical, except kurtosis. is possible kurtosis computed differently matlab , apache library? if so, data should trust then? edit my data subset of image matrix (containing pixels values). each subset compute above statistics. everytime, statistics match except kurtosis. the matlab...
