PMLE.SEF3.positive {double.truncation} | R Documentation |
Parametric Inference for the three-parameter SEF model (positive parameter space for eta_3)
Description
Maximum likelihood estimates and their standard errors (SEs) are computed. Also computed are the likelihood value, AIC, and other qnantities.
Usage
PMLE.SEF3.positive(u.trunc, y.trunc, v.trunc, tau2 = max(y.trunc),
epsilon = 1e-04, D1=20, D2=10, D3=1, d1=6, d2=0.5)
Arguments
