Visualize f distribution

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

vdist_f_plot(num_df = 4, den_df = 30, normal = FALSE, print_plot = TRUE)

vdist_f_perc(
  probs = 0.95,
  num_df = 3,
  den_df = 30,
  type = c("lower", "upper"),
  print_plot = TRUE
)

vdist_f_prob(
  perc = 2.35,
  num_df = 5,
  den_df = 32,
  type = c("lower", "upper"),
  print_plot = TRUE
)

Arguments

num_df	Degrees of freedom associated with the numerator of f statistic.
den_df	Degrees of freedom associated with the denominator of f statistic.
normal	If TRUE, normal curve with same mean and sd as the F distribution is drawn.
print_plot	logical; if TRUE, prints the plot else returns a plot object.
probs	Probability value.
type	Lower tail or upper tail.
perc	Quantile value.
