Collection of statistical formulas for professional and other bachelor studies. Also useful for Master and PhD studies where statistics is applied. Contains formulas from basic combinatorics, probability and statistical data summation including linear regression. Covers the a decent set of probability distributions, with good instructions on how to calculate them using some popular software packages (R, Excel, Mathematica) and scientific calculators (even when they are not explicitly present on these calculators). Has a large selection of both Bayesian and frequentist inference formulas. The 2020 edition differs from the 2019 edition primarily in support for R and Excel. Both of these further differ significantly from the 2018 edition by utilizing and organizing by the process Bernoulli (binomial), Poisson, and Gaussian processes. Otherwise smaller changes intended to increase user friendliness by half a percent.
