We are delighted to announce that both Luis Ledesma and Di Shan successfully defended their Masters’ thesis in September.<\/p>\n

Luis’ thesis was titled “Intercept estimation of semi-parametric joint models in the context of longitudinal data subject to irregular observations<\/em>“; in it Luis showed how to extend previous multiplicative models for longitudinal outcomes and irregular observation times to estimate intercepts. Besides providing valuable information on prognosis, this also reduces computation time.<\/p>\n

Di’s thesis was titled “Variable Categorization and Selection in the Context of Inverse-Intensity Weighting for Longitudinal data”;\u00a0<\/em>Di showed that adding variables associated with the outcome but not the intensity to the intensity model improves the precision of inverse-intensity weighted GEEs, while adding variables associated with the intensity but not the outcome to the intensity model inflates the variance of regression coefficients from inverse-intensity weighted GEE<\/p>\n","protected":false},"excerpt":{"rendered":"
