  1. The sample size (N) and shape parameter (Sh.) of the Weibull function are indicated for each model, as well as the parameter estimate (Est), its standard error (SE), z statistic, and p for each covariate. Rec Cond stands for conditions experienced upon recruitment. With (Yearling), the corrections for the intercept and trends estimated for that group are indicated.
