gaussratiovegind

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:

• Probability density function
• Sample simulation
• Parameter estimation

An example on the study of chlorophyll fluorescence can be found in A. El Ghaziri et al. (2023)

Installation

Install the package from CRAN:

install.packages("gaussratiovegind")

Or install the development version from the repository, using the devtools package:

install.packages("devtools")
devtools::install_gitlab("imhorphen/gaussratiovegind",
                         host = "https://forgemia.inra.fr")
