If ψiψi is log-normally distributed, the 3 following representations are equivalent:log(ψi)log(ψi)ψi∼(log(ψpop) ,ω2)=log(ψpop)+ηi=ψpopeηilog(ψi)∼N(log(ψpop) ,ω2)log(ψi)=log(ψpop)+ηiψi=ψpopeηiLogit-normal distribution:The logit function is defined on (0,1)(0,1) and take its value in ℝR: For any xx in (0,1)(0,1),logit(x)=log(x1−x)⟺x=11+e−logit(x)logit(x)=log(x1−x)⟺x=11+e−logit(x)An individual parameter ψiψi with a logit-normal distribution takes its values in (0,1)(0,1). 42183639 0.

The platform of the nonlinear mixed effect models can be extended to consider the spatial association by incorporating the geostatistical processes such as Gaussian process on the second stage of the model as follows:10
