1. A brief summary of the statistical method (1) What is the method? Regression is a statistical technique used for modeling and analysis of numerical data by finding the best-fitting straight line. In other words, a regression line is defined the combination between the average values of a numerical outcome variable and deterministic variables. The ways to find a best fitting straight line, es...

Model trees are an extension of regression trees that associate leaves with multiple regression models. In this paper a method for the top-down induction of model trees is presented, namely the Stepwise Model Tree Induction (SMOTI) method. Its main characteristic is the induction of trees with two types of nodes: regression nodes, which perform only straight-line regression, and split nodes, wh...

Table A2 shows the results of the Nijman-Verbeek test for sample selection in panel models. This test examines the possibility of selection bias in unbalanced panel data. We construct two indicator variables. First, the lagged selection indicator “inlastyr” indicates that a firm present in year t of the sample period is also present in year t – 1. Second, the forward selection indicator “innext...

BACKGROUND Treatment for metastatic castrate-resistant prostate cancer in community settings is not well understood. OBJECTIVE To examine treatment patterns, sequencing, and outcomes in patients receiving second- and third-line treatment after first-line docetaxel. METHODS We used a community oncology database to identify patients who progressed after line 1 docetaxel (D) and received line ...

Abstract A smooth manipulator motion is desired to work cooperatively with human hand in transferring an object. In this article, a relationship between movement time and traveled distance of a cooperative object transfer performed by two humans using their right hands in a seated position was investigated. The relationship will be utilized with a minimum jerk model to generate a smooth coopera...

This paper derives an identity connecting the square loss of ridge regression in on-line mode with the loss of the retrospectively best regressor. Some corollaries about the properties of the cumulative loss of on-line ridge regression are also obtained.

Businesses around the world face the challenge of identifying, attracting and retaining customers in the cybermarket, as well as converting lookers to bookers. Most of the consumer behaviour research has been conducted for European and American on-line segments. As these markets approach on-line maturity, marketers seek new and emerging markets to expand their offering. China is one of these ma...
