Notes: Standard errors are in parentheses. * denotes significance at the 10 percent level, ** significance at the 5 percent level, and *** significance at the 1 percent level. Replications for simulated probability were 500. AGE = age of the respon- dent; ASC = alternating specific constant; EAST = whether or not the household is in the Eastern Region; EDUC = whether or not the respondent has postsecondary education; GM = genetically modified; GROW = whether or not the household grows bananas; HHSIZE = household size; INCOME = log of monthly household income; SWEST = whether or not the household is in the Southwestern region.
