Coefficient estimates and standard errors of the parameters included in the most plausible model for the effect of the treatments on survival time of Erythrina velutina seedlings in the field experiment.

The model has survival time as Weibull distribution with experimental blocks as frailt model with Gaussian distribution. Model coefficients: control (int); presence of Leucaena leucocephala (leu), presence of Capparis flexuosa (cap), interaction (leu:cap) and log scale (lsc), a Weibull fixed parameter.
