gibbs3f90

How does the programwork? number of samples and length of burn-in? In the first run, if you have no idea about the number of samples and burn-in, just type your guess (10000 or whatever) for samples and (0) for burn-in. You may need 2 or 3 runs to figure out the convergence. Give n to store every n-th sample? Gibbs samples are usually highly correlated, so you do not have to keep all samples. Maybe every 10th,20th, 50th, ... To check the convergence and to calculate posterior means and SD, run postgibbsf90. How do OPTIONs for heterogeneous residual variances work? OPTION hetres_int 5 10 The position (5) to identify the interval in the data file and the number of intervals (10) for heterogeneous residual variances. How do OPTIONs work? OPTION fixed_var all 1 2 3 All solutions and posterior means and SD for effects for effects1, 2, and 3 are stored in "all_solutions" and in "final_solutions" every round using fixed variances. Without numbers, all solutions for all effects are stored. OPTION fixed_var mean 1 2 3 Posterior means and SD for effects1, 2, and 3 in "final_solutions". OPTION solution all 1 2 3 All solutions and posterior means and SD for effects1, 2, and 3 are stored in "all_solutions" and in "final_solutions" every round. Without numbers, all solutions for all effects are stored. OPTION solution mean 1 2 3 Posterior means and SD for effects1, 2, and 3 in "final_solutions". OPTION cont 10000 10000 is the number of samples run previously when restarting the program from the last run. OPTION prior5 5 is the degree of belief for the priors specified in the parameter file. OPTION seed123 321 Two seeds for a random number generator can be specified. OPTION SNP_filesnp Specify the SNP file name to use genotype data. Need more examples?
