Parameter identifiability is required in pooled data methods.
In pooled data methods such as naive pooled data methods and NONMEM, the number of sample points per individual may be less than the number of unknown parameters so that the values of the parameters are not estimable in individuals. However, for the moments of the distributions of the parameters to be estimable, the basic parameters must be identifiable.
