Test of mean orientations

Source: R/vector_stats.R
fisher_ftest.Rd

Test against the null-hypothesis that the samples are drawn from the same Fisher population.

Usage

fisher_ftest(x, y, alpha = 0.05, na.rm = TRUE)

Arguments

x, y

objects of class "Vec3", "Line", or "Plane", , where the rows are the observations and the columns are the coordinates.

alpha

numeric. Significance level for the confidence angle (default is 0.05 for a 95% confidence angle).

na.rm

logical. Whether NA values should be removed before the computation proceeds.

Value

list indicating the F-statistic and the p-value.

Examples

set.seed(20250411)
x <- rvmf(100, mu = Line(120, 50), k = 20)
y <- rvmf(100, mu = Line(180, 45), k = 20)

stereoplot()
stereo_point(x, col = 1)
stereo_point(y, col = 2)
