dist_f_plot: Visualize f distribution In rsquaredacademy/descriptr: Generate Descriptive Statistics & Explore Statistical Distributions

Description

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.

Usage

 ```1 2 3 4 5 6``` ```dist_f_plot(num_df = 4, den_df = 30, normal = FALSE) dist_f_perc(probs = 0.95, num_df = 3, den_df = 30, type = c("lower", "upper")) dist_f_prob(perc, num_df, den_df, type = c("lower", "upper")) ```

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. `probs` Probability value. `type` Lower tail or upper tail. `perc` Quantile value.

Value

Percentile for the `probs` based on `num_df`, `den_df` and `type` or probability value for `perc` based on `num_df`, `den_df` and `type`.

Deprecated functions

`f_plot()`, `f_prob()` and `f_per()` have been deprecated. Instead use `dist_f_plot()`, `dist_f_prob()` and `dist_f_perc()`.
