StatsBase.jl Release Notes

Changes from v0.5 to v0.6

  • Support of weighted sampling without replacements

  • Implement several new sampling algorithms and a new polyalgorithm for sampling (for both with and without replacements). The new polyalgorithms choose the proper routine depending on the size of the pool and the number of samples to be drawn. (See documentation). The choices are determined based on benchmarks.

  • New function scattermat: scatter matrix and weighted scatter matrix.

  • Weighted covariance matrix.

  • Weighted variance and standard deviation (both over an entire array or along a given dimension).

  • The function middle is moved to Julia Base.

  • Functions to compute certain combinations of statistics (more efficiently): mean_and_var, mean_and_std, and mean_and_cov.

  • New function zscore: computation of z-scores.

Changes from v0.6 to v0.7

  • Remove functions deprecated before v0.5: gmean, hmean, kde, acf, ccf and indicators.

  • Add functions to compute deviations (moved from MLBase): countne, counteq, sqL2dist, L2dist, L1dist, Linfdist, gkldiv, meanad, maxad, msd, rmsd, and psnr (See documentation here).
