Computes (batch-wise) sample statistics.
Project description
pyBatchedMoments
pyBatchedMoments is a Python library for computing (batch-wise) sample statistics, such as mean, variance, standard deviation, skewness and kurtosis.
In certain applications it is needed to compute simple statistics of a population, but with textbook formulae the calculation can suffer from loss of precision and can be numerically unstable. Additionally, for large populations only a single pass over the values is feasible, therefore, an incremental (batch-wise) approach is desirable.
Install
To install the current release

data = [2, 8, 0, 4, 1, 9, 9, 0]
bm = BatchedMoments()
bm(data)
# use computed values
bm.mean
bm.std
