Exploring Correlation Coefficients with Golf Statistics

This article explores the relationships between several pairs of statistics kept on professional golfers on the PGA tour. Specifically, two measures related to the player's ability to drive the ball are compared as are two measures related to the player's ability to putt. An additional analysis is made between one statistic related to putting and another that measures how effectively the player tends to reach the green. An analysis of which statistic has the most impact on a player's score is also included. The article concludes with an interesting extension relating the statistics of professionals to the performance of an amateur golfer.

一种检验相关系数相等性的精确方法

研究了多个相互独立的二元正态分布相关系数的相等性检验问题。定义了一个新的广义检验变量,给出了检验问题的广义p值。这种方法不依赖于大样本近似,而且可以算出广义上的精确p值,弥补了传统方法不适用于小样本的缺陷。     

Comparing Squared Multiple Correlation Coefficients Using Structural Equation Modeling

In social science research, a common topic in multiple regression analysis is to compare the squared multiple correlation coefficients in different populations. Existing methods based on asymptotic theories (Olkin & Finn, 1995) and bootstrapping (Chan, 2009) are available but these can only handle a 2-group comparison. Another method based on structural equation modeling (SEM) has been proposed recently. However, this method has three disadvantages. First, it requires the user to explicitly specify the sample R² as a function in terms of the basic SEM model parameters, which is sometimes troublesome and error prone. Second, it requires the specification of nonlinear constraints, which is not available in some popular SEM software programs. Third, it is for a 2-group comparison primarily. In this article, a 2-stage SEM method is proposed as an alternative. Unlike all other existing methods, the proposed method is simple to use, and it does not require any specific programming features such as the specification of nonlinear constraints. More important, the method allows a simultaneous comparison of 3 or more groups. A real example is given to illustrate the proposed method using EQS, a popular SEM software program.     

与组合性述补短语有关的三个问题

本文讨论三个问题:1."状+地+动"是描写性地叙述一个过程,"动+得+补"是说明一个过程造成什么结果.2."动+得+补"中"动"既可以是旧信息,也可以是新信息.说话时选择哪种信息安排方式,取决于一些语义或表达的因素,文章观察了这些因素.3.在"动+得+补"句式教学中,应该重视"动"的信息性质,重点讲"动"是旧信息的类型,也即用两个句子表达过程及其结果.文章为"动+得+补"概括出的"前+(中)+后"篇章环境在"动+得+补"格式教学上会有多方面的积极作用.     

附加性联合短语初探

朱德熙先生依据功能将联合短语划分为体词性的和谓词性的两大类。我们认为，除了体词性和谓词性以外，现代汉语中还存在这样一些联合短语，它们在功能上既不同于体词性，也不同于谓词性，而是具有明显的附加性特征。所以，我们尝试将它们另立一类，名为“附加性联合短语”。文章主要讨论这类联合短语的小类与功能。

RK方程的系数随温度变化对氧气热力学性质的影响

用热力学方法,应用实验结果研究了RK方程中RK系数随温度改变及其对氧气的内能、焓等热力学性质和摩尔热容量之差的影响。结果表明,氧气的状态应当用实际气体的状态方程例如RK方程描述,不同温度下的采用相应的RK系数才能更加符合实际;当温度很低例如低于临界温度时,两种不同的RK系数导致的相关结果相差很大;当温度高于300K时,两种不同的RK系数导致的相关结果的差异可忽略不计。     

结合犯立法刍议

结合犯是大陆法系中普遍存在的一种基本罪数形态，但在我国的刑法体系中，还没有典型的结合犯立法例，这也造成了我国刑事司法中部分犯罪的罪名和罪数认定的混乱，为解决这种罪数和罪名认定上的混乱，合理规范法官的自由裁量权，防止司法擅断，同时也为了保证对犯罪分子的宣告罪名更加真实直观地反映犯罪分子的犯罪行为，在我国刑法中有必要增加结合犯的立法例，以促进我国刑事立法的进一步完善。

Designing SQL Database Modules Using Correlation Coefficients and Linear Regression: A Content‐Centered Approach

Information systems educators are increasingly incorporating business intelligence and analytics topics into information systems training. Educators often create modules independently, which can be difficult to effectively design given most information systems trainers have no formal training in instructional design. This article incorporates a content‐centered design model, pebble‐in‐the‐pond (Merrill, 2002 ), and provides an example of the design process using the topic of predictive analytics that information systems educators can follow to create instructional modules using sound instructional design considerations.
