Refer to the pig farmer survey of Problem 11.7 (Table 11.1 1). Analyze these data using marginal models with all the variables.
Data from Problem 11.7:
Table 11.11 is from a Kansas State University survey of 262 pig farmers. For the question “What are your primary sources of veterinary information?,” the categories were (A) professional consultant, (B) veterinarian, (C) state or local extension service, (D) magazines, and (E) feed companies and reps. Farmers sampled were asked to select all relevant categories. The 25 × 2 × 4 table shows the (yes, no) counts for each of these five sources cross-classified with the farmers’ education (whether they had at least some college education) and size of farm (number of pigs marketed annually, in thousands).
