plot_F_test: Plot F Test to Compare Two Variances

In Zibetti/Plothtests: Plot Parametric Hypothesis Tests (Z, T, Chi-squared and F)

Description

Plot F Test to Compare Two Variance, the larger sample variance is always placed in the numerator.

Usage

plot_F_test(alpha = 0.05, alternative = "two.sided", df1, df2, v1, v2,
  ratio = 1, annotations = TRUE, color = 3)

Arguments

alpha	significance level for the critical limits
alternative	a character string specifying the alternative hypothesis, must be one of "two.sided" (default), "greater" or "less".
df1	degrees of freedom for the sample 1 (default = 10)
df2	degrees of freedom for the sample 2 (default = 10)
v1	sample 1 variance (default = 1.5)
v2	sample 2 variance (default = 2.5)
ratio	the ratio of population variances under the null hypoyhesis (default = 1)
annotations	logical, show annotations in plot figure, TRUE ou FALSE (default = TRUE)
color	integer, color theme for plot, from 1 to 7 so far (default = 3)

Examples

plot_F_test(alpha = 0.05, alternative = "two.sided",
            df1 = 10, df2 = 10,
            v1 = 1.5, v2 = 2.5,
            ratio = 1,
            annotations = TRUE,
            color = 3)
