dist_t: Visualize t distribution

Description

Visualize how degrees of freedom affect the shape of t distribution, visualize quantiles out of given probability and probability from a given quantile.

Usage

dist_t_plot(df = 3)
dist_t_perc(probs = 0.95, df = 4, type = c("lower", "upper", "both"))
dist_t_prob(perc, df, type = c("lower", "upper", "interval", "both"))

Arguments

df

Degrees of freedom.

probs

Probability value.

type

Lower tail, upper tail, interval or both.

perc

Quantile value.

Value

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