elative risks, as a function of those coefficients, is more challenging.</p>
<p>We first provide a estimated variance of relative risk using Delta method upon estimated variance of odds ratio from <code>glm</code>. The second method to estimate variance is using sampling variance of bootstrap samples.</p>
