Test for equality of concentration parameters for spherical data
Description
This tests the equality of concentration parameters for spherical data only.
Usage
spherconc.test(x, ina)
Arguments
x
A matrix with the data in Euclidean coordinates, i.e. unit vectors
ina
A variable indicating the groupings of the observations.
Details
The test is designed for spherical data only.
Value
A list including:
mess
A message stating the value of the mean resultant and which test statistic was used, U1, U2 or U3.
res
A vector containing the test statistic and its p-value.
