%description
It provides classifiers which can be used for discrete variables and for
continuous variables based on the Naive Bayes and Fuzzy Naive Bayes
hypothesis. Those methods were developed by researchers belong to the
'Laboratory of Technologies for Virtual Teaching and Statistics (LabTEVE)'
and 'Laboratory of Applied Statistics to Image Processing and
Geoprocessing (LEAPIG)' at 'Federal University of Paraiba, Brazil'. They
considered some statistical distributions and their papers were published
in the scientific literature, as for instance, the Gaussian classifier
using fuzzy parameters, proposed by 'Moraes, Ferreira and Machado' (2021)
<doi:10.1007/s40815-020-00936-4>.
