Note. Solv is the probability of remaining fiscally solvent, Cure is the probability of cure, Class share is the proportion of the population that falls into each segment, and P for difference is the statistical significance of the difference between the coefficients on Solv and Cure within each segment. The ratio of coefficients gives the relative weight that individuals place on cure vs. financial solvency. That is,individuals represented by class 1 find cure 5.8 times more important than solvency, where as individuals represented by class 3 find solvency 87.4 times more important than cure. Note that the coefficients represented here are scaled such that “Cured and Solvent” has a utility of 1.0.
CI, confidence interval; SE, standard error.
Because the 95% CI for individual preference weights crosses 0 in classes 1 and 4, the 95% CI for the importance ratio is undefined.
