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", "Ray", 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)
