Abstract

In this paper, we show that a two component Laplace mixture model is an appropriate distribution to model postoperative calcium levels of patients undergoing thyroidectomy or surgery for thyroid diseases. A mixture regression model is constructed to predict postoperative calcium levels based on a pre-determined set of potential predictors. The parameters of the model are estimated using EM algorithm. Our study based on a real data set shows that two component Laplace mixture regression model is suitable for prediction and interpretation compared to the usual Gaussian mixture regression model.
