# Features #
############

- Computation of Gaussian Copula correction terms, using their ECDF (Park & Gupta 2012)
- Estimation of Feasible Generalized Least Squares (FGLS) with unbalanced panels
- Estimation of market share attraction models (Fok 2001)
  o Transformation of wide panels into their base-brand representation
  o Support for homogenous and heterogenous coefficients
  o Restricted competition; fully extended model not implemented
  o Estimation via itersur() (FGLS)
