- Non-convergence example for maximum likelihood estimation
- Files corresponding to the marginal modeling approach examples given in Section 4.1 of the paper:
- control_2MRCV_final.sas - This is the control program for the statistical methods. Use this program to run the programs boot_2MRCV_final.sas, data_gen_resample.sas, and gange_2MRCV.sas.
- 2_MRCV_example_data.txt - Data set for test waste and waste storage only.
- boot_2MRCV_final.sas - Fits a generalized loglinear model via the marginal modeling method and use the bootstrap and Rao-Scott approximations to find a p-value for testing the model of interest vs. the saturated model.
- gange_2mrcv.sas - Finds a vector of multinomial probabilities subject to the constraints of the H
_{o}model. - data_gen_resample.sas - Using a set of multinomial probabilities from Gange.sas, this program
generates the resamples under the H
_{o}model

- Files corresponding to the marginal modeling approach examples given in Section 4.2 of the paper.
- control_3MRCV_final.sas - This is the control program for the statistical methods. Use this program to run the programs boot_3MRCV_final.sas, data_gen_resample.sas, and gange_3MRCV.sas.
- 3_MRCV_example_data.txt - Data set for test waste, waste storage, and sources of veterinary information MRCVs.
- v_mat_m.csv - File containing the V matrix (see Appendix A) used in the PROC IML code of boot_3MRCV_final.sas and read in control_3MRCV_final.sas (see program comments for more information).
- boot_3MRCV_final.sas - Fits a generalized loglinear model via the marginal modeling method and use the bootstrap and Rao-Scott approximations to find a p-value for testing the model of interest vs. the saturated model.
- gange_3MRCV.sas - Finds a vector of multinomial probabilities subject to the constraints of the H
_{o}model. - data_gen_resample.sas - Using a set of multinomial probabilities from Gange.sas, this program
generates the resamples under the H
_{o}model. This is the same program as listed in the Section 4.1 programs.
