pcce
is a function for the estimation of linear panel models by
the Common Correlated Effects Mean Groups or Pooled estimator,
consistent under the hypothesis of unobserved common factors and
idiosyncratic factor loadings. The CCE estimator works by
augmenting the model by cross-sectional averages of the dependent
variable and regressors in order to account for the common factors,
and adding individual intercepts and possibly trends.
