Question

1. the men in the study were classified as to whether or not they had myopia, and whether at least one of their parents had myopia. The results are presented in the table below:

	Subject has myopia
At least one parent has myopia	Yes	No
Yes	223	23
No	155	28

Let x be the indicator variable: 0 = at least one parent does not have myopia, 1 = at least one parent has myopia. We wish to fit a logistic regression model, log(p/(p-1)) = beta zero + beta one X, where p is the binomial probability that a man in the Singapore military has myopia and log is the natural logarithm.

a. What are the odds that a man with at least one parent with myopia also has myopia?

2. What is the estimate of β₀?
3. What is the estimate of β₁?
4. What is the odds ratio?
