Prediction with some naive Bayes classifiers for circular data.
vmnb.pred(xnew, mu, kappa, ni)
spmlnb.pred(xnew, mu1, mu2, ni)A numerical vector with 1, 2, ... denoting the predicted group.
A numerical matrix with new predictor variables whose group is to be predicted. Each column refers to an angular variable.
A matrix with the mean vectors expressed in radians.
A matrix with the first set of mean vectors.
A matrix with the second set of mean vectors.
A matrix with the kappa parameters for the vonMises distribution or with the norm of the mean vectors for the circular angular Gaussian distribution.
The sample size of each group in the dataset.

Each column is supposed to contain angular measurements. Thus, for each column a von Mises distribution or an circular angular Gaussian distribution is fitted. The product of the densities is the joint multivariate distribution.
