%description
It is well known that the distribution of a Gaussian ratio does not follow
a Gaussian distribution. The lack of awareness among users of vegetation
indices about this non-Gaussian nature could lead to incorrect statistical
modeling and interpretation. This package provides tools to accurately
handle and analyse such ratios: density function, parameter estimation,
simulation. An example on the study of chlorophyll fluorescence can be
found in A. El Ghaziri et al. (2023) <doi:10.3390/rs15020528> and another
method for parameter estimation is given in Bouhlel et al. (2023)
<doi:10.23919/EUSIPCO58844.2023.10290111>.
