Estimating multiple regression model; GCC countries Statistics Project

Estimating multiple regression model; GCC countries - Statistics Project Example The assignment will conduct a multiple regression analysis using the data from observations for a period from 1999 – 2012. The multiple regression analysis is a technique of statistics that is used to develop a linear model for predicting the unknown value of a variable from known or assumed values of independent variables. In this case, the model Y = ∠« (Xa, Xb); where Y = GDP per capita, Xa = FDI, and Xb = Export is represented by the equation Y = b0 + b1Xa + b2Xb. The task of the multiple regression analysis is to determine the values of parameters a, b1, and b2. In order to it, the assignment collected data for Xa, Xb, and Y for years from 1999 – 2002. Table 1 presents data set; values will be used for regression analysis. The sample data of table 1 is collected from the annual reports published by the Qatar Central Bank (â€Å"Annual Reports†, n.d.) and Index Mundi (â€Å"GDP†, n.d,; â€Å"Exports†, n.d)). The set represent values of three variables collected from 14 observations. These values will be used to find a regression line that best fits the data illustrated in Table 1. The regression coefficients of variables as well the intercept of the regression equation are calculated using Excel functions. The parameter calculation method does not consider the noise in regression analysis. This study does not conduct sample data distribution phenomenon; however, it does conduct a study of Goodness of fit of the model. The given data are used to conduct descriptive and inferential analyses. Descriptive coefficients characterizes the data set; the concept represents the central tendency and dispersion of data taken from observations. Inferential analysis, in this case, describes the behavior and authentication of the model through hypothesis testing of regression parameters. Descriptive statistics of all three variable are evaluated using Excel built in function; they are presented in Table 2.

Bilingualism theories and deaf - Assignment Example The thresh hold theory on the other hand provides a three staged development of bilingual abilities the theory explains that bilinguals achieve positive cognitive advantages after crossing the first and the second threshold (Baker, 2011) (Page# 167 lines#26-30). Developed in 1977 by Toukomaa and Skutnabb-Kangas, the threshold theory analyses the relationship between bilingualism and cognitive development. Language is a social tool used in enhancing interactions. As such, the development of bilingualism in children is always a portrayal of their cognitive development. In analyzing bilingualism, the theory provides three stages of bilingualism development that also portrays the development of cognition in children (Baker, 2011) (page#167 lines # 24-29). Each of the three thresholds is varying levels of language competencies that also portray the cognitive development of a child. Stage 1 is a preliminary stage and children at such stages lack effective bilingual skills thus cannot communicate effectively. At such stages, children have weak cognitive development. Their inability to speak in two languages is therefore a portrayal of their underdeveloped cognitive abilities. According to the theory, the second thresh hold is also preliminary and the children cannot communicate in two languages effectively. The theory explains that people begin realizing the benefits of bilingualism. The theory uses the example of a child with progressive prowess of bilingualism. At the first two stages, the child cannot realize the benefits of bilingualism since they cannot communicate effectively. The fact that this portrays their underdeveloped cognitive prowess further complicates the situation. Such a child cannot for example use language to enhance learning in school. As such, his inability in bilingualism affects his academic development since such a student cannot learn effectively. After crossing the second threshold, the child

Project Management Methodology Essay Example | Topics and Well Written Essays - 3500 words

Project Management Methodology - Essay Example There are nearly four to five process groups in the project management methodologies. The process group comprises initiation, planning and design, execution, monitoring and controlling and closing (Haughey, 2012). The main objective of the report is to describe the project, which is â€Å"Privatisation of QinetiQ† by focusing upon the characteristics of the project that impact the choice of project management approach. The project will also discuss the use of numerous planning tools as well as techniques such as work breakdown structure, Gantt chart, critical path method as well as PERT approach to scheduling that has been used for this project. The report will proceed by identifying various risks that have been associated with the project and will discuss the utilisation of risk management methodology. The report will conclude by reflecting on what has been researched for this assignment and any implication with regard to bringing in changes for current or future practice as a project manager. QinetiQ is a defence technology business. It has been acknowledged that the privatisation of QinetiQ took place in two phases i.e. sale of 33.8 percent business to the Caryle Group and sale of 3.7 percent of the business to the management as well as employees. The total of 37.5 % of the business was sold in the year 2003. The main motto behind the privatisation was to assist in creating a business ahead of flotation on the London Stock Exchange that happened in the year 2006. The privatisation activity had assisted in gaining approximately  £576 million. It has further been found that Ministry of Defence has a holding of 19 percent in the business valued at  £235 million in the year 2007 (National Audit Office, 2008). QinetiQ possesses a significant role in conducting research and in suggesting the Department on the creation and the procurement of equipment. It also has a role
