Essays on Estimators

Abstract

This dissertation formulates a research dissertation and strategy for a study into the impact of Islamic banking on the economic development of societies within which such banks operates. To this end, the research examines the major tools and impacts of Islamic banks on society by conducting a literature review. This is followed by the deduction of research questions and a hypothesis that will be used to form the parameters of the entire research. The purpose of this dissertation is to investigate the relationship between the growth of Islamic banking worldwide and economic development of countries wherein this growth is ...

Summary

Interval estimators specify methods of measuring sample that can be used to determine endpoint values of an interval. Intervals have a target parameter, and they are relatively narrow. At least one endpoint varies randomly since they are sample measurement functions. Interval estimators are confidence intervals with lower and upper limits. Confidence coefficient is the probability of intervals having a target parameter.

Hypothesis testing is a procedure of using observations to test theories. Theories concerning population parameters are sampled and compared with observations. If observations do not match with the theory, the hypothesis is rejected as false, otherwise the theory is true. Hypothesis ...

Biometrika has fro the last 100 years published over 400 years concerning the subject of Time Series. Time series is a significant feature in Biometrika under the editorship of Professor E.S. Pearson. These papers grew enormously at a rate of 10% up to the present time. The first Time series paper was written by Gosset “student” and Anderson (1914). Correlation was a new and a crucial concept in Time series. Consider two time series, (Xt) and (Yt) as expressed below Xt = mt +et and Yt = Mt + Et Where et and Et are sequences of uncorrelated random variables, mt and Mt ...

Introduction

Poverty is the deprivation of basic things like money, food or assets that are essential for a normal life. GDP on the other hand is the goods and services produced within the by a country in a year. It is known that with increase in poverty it leads to reduction in output of a country. This is because essential resources that are vital for production are lacking. It also means that human capital is insufficient and consequently the resources needed to stir growth are used to feed and provide for the poor population. Poverty and unstable GDP are common phenomena in developing ...

Abstract

Econometrics analysis is crucial in developing models that are useful in estimating economic variables. However, development of suitable models is crucial in ensuring that their forecasts are accurate. That involves applying suitable model estimation techniques as well as testing for the estimated parameters’ significance. This study applies multiple regressions to analyze the determinants’ of CPI in United Arab Emirates considering the economy’s data for 30 years with an objective of establishing those factors that have a significant effect on CPI. In that respect, the study analyzes five variables including GDP per capita growth (annual %), Money and Quasi money (M2) ...

Introduction

The main objective of this paper is to apply statistical techniques learned in the course. For the purposes of the current paper Bank of America was chosen. The Bank experienced hard times during mortgage crisis of 2007-2008. The statistical techniques proposed in this paper are earmarked for reduction of mortgage risk. An implementation plan for application chosen statistical technique was developed. Statistical technique will be applied according to timetable that was enclosed in the paper. Also, there were financial, human, technical, and other resources identified for the implementation plan. The implementation plan contains the information needed for application the ...

Introduction

Over the past decade, there have been dozens of quantitative studies dealing with the onset of civil wars. Through the quantitative studies on civil wars, significant determinants have been proven statistically. This has been possible through the separate studies on the duration and onset of civil war as the determinants for these two processes are different. However, the separate studies have often resulted in the difficulty to find the any statistically significant association between the onset and duration of the war. This due to the selection effect, which has continually been inherent in the duration models, which make it ...
