R Documentation
Marginal density function for the longitude of the SNNTS model for spherical data
Description
Marginal density function for the longitude of the SNNTS model for spherical data
Usage
snntsmarginallongitude(data, cpars = 1, M = c(0,0))
Arguments
data
Vector of angles in radians, with one row for each data point. The data must be between zero and 2*pi
cpars
Vector of complex numbers of dimension prod(M+1). The first element is a real and positive
number. The first M[1]+1 elements correspond to longitude, and the next M[2]+1 elements correspond to latitude.
The sum of the squared moduli of the c parameters must be equal to one.
M
Vector with number of components in the SNNTS for each dimension
Value
The function returns the density function evaluated for the data
Note
The parameters cpars used by this function are the transformed parameters of the SNNTS density
function, which lie on the surface of the unit hypersphere
