A stepwise logistic regression analysis was performed in 27 cases of papillary carcinoma thyroid (PC), 20 follicular neoplasms (FN), 30 cases of Grave's disease (GD), and 40 cases of colloid adenomatous goitre (CAG). The three most important variables in predicting PC were papillary clusters, dense

β¦ Synopsis
This paper presents a basic loss minimization model which has been applied in varying contexts for Polaris logistics problems. Definitive results a r e obtained in a general framework which extends the classic newsboy problem in two principal directions. F i r s t , probability distributions for demand a r e unrestricted. Second, a general framework for "penalties" o r "premiums" is introduced to permit formulation of possibly non-convex loss functions. The main result is a constructive existence theorem for minimum values of these general expected loss functions.
'%-I the following we suppose that the mean m exists as a finite quantity in order to avoid unrewarding complications.
