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. If TRUE, normal curve with same mean and sd as the chi square distribution is drawn. Probability value. Lower tail or upper tail. Quantile value.
