| exposure-response relationship for a dichotomized response when the continuous underlying variable is not measured. | radiological assessment of pneumoconiosis is an example of a dichotomized variable, namely one that is analysed as a binary response but in fact has an underlying continuum, which in this case is not measurable. estimates of exposure-response relationships vary greatly for different observers of a dichotomized response variable because of random error of measurement and differences in the threshold implicitly chosen by each observer for categorizing cases. we present a method of using the biseri ... | 2011 | 3175395 |
