      The likelihood ratio test comes directly from the likelihood equation in Maximum Likelihood Estimation. When the model is fit with only the intercept (no predictors), the value of the likelihood equation (the probability of our data) at its maximum value is 9.9090187 × 10-111, which translates to a -2LogLikelihood (-2LogL) of 506.587.

    • Answers to Practice Problems

      The odds ratio is computed very easily from tables as observed in this problem. We first identify each cell within the table as follows: We then take the values in each cell identified as a,b,c and d and . compute the odds ratios for each risk factor as follows: We now compute the 95% confidence intervals for these odds ratio estimates as follows.

      5. The Mantel-Haenszel adjusted odds-ratio. Is used to summarize the stratum specific OR’s to correct for confounding (when there is no effect modification). (If there is EM we do not summarize the strata. We keep the strata separate.) CRUDE odds-ratio = ad/bc . Mantel-Haenszel adjusted odds-ratio= numerator/denominator

      Know how to interpret the regression coefficients, the B's, in terms of log odds and as odds ratios on the transformed scale. Be aware of the difference in interpretation for indicator versus continuous variables. In particular remember that you can get an odds ratio corresponding to any change, delta, in an X value for a continuous variable.

      This odds ratio is the crude estimate because we did not adjust for any. other covariates. (b) Now adjust for age by stratification into the 6 age categories. Determine and interpret an adjusted odds ratio for tobexp and a 95% confidence limit using the Mantel-Haenszel method.

      The resulting adjusted odds ratio for TOB is given by: exp(0.488) = 1.63. This odds ratio is the increase in the odds of disease for a 1 unit increase in TOB categories, where age is controlled (ie. held fixed).
