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.

dist_chi_plot(df = 3, normal = FALSE)

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

dist_chi_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.

## Value

Percentile for the probs based on df and type or probability value for perc based on df and type.

## Deprecated functions

chi_plot(), chi_prob() and chi_per() have been deprecated. Instead use dist_chi_plot(), dist_chi_prob() and dist_chi_perc().
