Question:

6.2. Below are the results from a Poisson regression model. INDEPENDENT VARIABLE b SE z Intercept 1.25 0.15 8.33 x1 0.13 0.06 2.17 x2 0.46 0.08 5.75 x3 0.05 0.04 1.25 (a) Assume that the quasi-Poisson over-dispersion parameter, θ, is 2.00. Adjust the standard errors using this value. (b) Compute over-dispersion adjusted z-values. (c) Assuming that the z critical value for a .05 significance level is 1.96, how do the results change after adjusting for over-dispersion? (d) Compute the percent change associated with a one-unit change in each of the independent variables?
