formula |
A symbolic description of model to be fitted |
data |
An object of class FLTable. |
The DB Lytix function called is FLMixedModelUdt or FLMixedModelIntUdt. The mixed model extends the linear model by allowing correlation and heterogeneous variances in the covariance matrix of the residuals. Fita a linear mixed-effects model (LMM) to data, FLMixedModelUdt and FLMixedModelIntUdt estimates the coefficients and covariance matrix of the mixed model via expectation maximization method.
