Visualize how changes in degrees of freedom affect the shape of the chi square distribution. Compute & visualize quantiles out of given probability and probability from a given quantile.

vdist_chisquare_plot(df = 3, normal = FALSE)

vdist_chisquare_perc(probs = 0.95, df = 3, type = c("lower",
  "upper"))

vdist_chisquare_prob(perc, df, type = c("lower", "upper"))

Arguments

df

Degrees of freedom.

normal

If TRUE, normal curve with same mean and sd as the chi square distribution is drawn.

probs

Probability value.

type

Lower tail or upper tail.

perc

Quantile value.
