Innovations in Financial Management: Recursive Prediction Model Based on Decision Trees

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

Branches in random recursive k-ary trees

In this paper, using generalized {polya} urn models we find the expected value of the size of a branch in recursive $k$-ary trees. We also find the expectation of the number of nodes of a given outdegree in a branch of such trees.

Degrees in $k$-minimal label random recursive trees

This article describes the limiting distribution of the degrees of nodes has been derived for a kind of random tree named k-minimal label random recursive tree, as the size of the tree goes to infinity. The outdegree of the tree is equal to the number of customers in a pyramid marketing agency immediatly alluring

A Practice Innovations Decision Model

Objective The purpose of this commentary is to propose a flexible practice innovations decision model (PIDM) for use in health services planning and management. Method This is an example of fuzzy decision analysis. The elements of the model are explained by applying it to the decision of whether to open a primary care clinic in retail space. The model contains 10 criteria, each of which score...
