vdist_t: Visualize t distribution

In vistributions: Visualize Probability Distributions

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

vdist_t_plot(df = 3, print_plot = TRUE)

vdist_t_perc(
  probs = 0.95,
  df = 4,
  type = c("lower", "upper", "both"),
  print_plot = TRUE
)

vdist_t_prob(
  perc = 1.6,
  df = 7,
  type = c("lower", "upper", "interval", "both"),
  print_plot = TRUE
)

Arguments

df	Degrees of freedom.
print_plot	logical; if TRUE, prints the plot else returns a plot object.
probs	Probability value.
type	Lower tail, upper tail, interval or both.
perc	Quantile value.
