Summary[edit]

DescriptionChi-square cdf.svg	English: Plot of the cumulative chi-square distribution for values of k = {1, 2, 3, 4, 6, 9}. Accurate plotcurves. Labels are embedded in Computer-Modern font. $f_{k}(x)=\int _{0}^{x}{\frac {t^{{\frac {k}{2}}-1}\cdot e^{-{\frac {1}{2}}t}}{2^{\frac {k}{2}}\cdot \Gamma ({\frac {k}{2}})}}\,\mathrm {d} t$
