Table 3.
The average estimated regression coefficients, the percentage of the estimated regression coefficients greater than zero, and the percentage of the estimated regression coefficients are significantly different from zero at level of significance, over 500 datasets simulated from the LFR2 method, with the second stage model being a negative binomial regression model.
