Autocorrelation

best fit the NHS data, we must examine several items: correlation of the data, existence or absence of trend and/or seasonality and stationarity of data. Autocorrelation is the examination of the correlation of data between successive observations over time (Wilson, Keating, & John Galt Solutions, 2009, p. 84). Figure 2 shows the autocorrelation factor (ACF) for the NHS data set. Because all the data is above the upper limit line, there appears to be a positive trend present for the 12-month forecast

A MC is often used due to its high accuracy along with the better capability of reproducing statistical properties of wind speed, and this is the approach selected for my study. Moreover, the use of energy storage in the system makes it essential to capture the correlation structure within the time series over time, which again favours the use of the MC. I provide the definition of a MC here, but details of this method will be discussed in Section 4.1. A MC is a sequence of random variables $\{X_{t}\}_{t

imperative to discuss seasonality, which is a commonly observed characteristic in energy markets. In order to assess whether there is actually an underlying pattern prevailing in the return an autocorrelation test can be easily carried out for verification. As explained in [10], the evidence of high autocorrelation manifests an underlying seasonality. On the contract, if the returns were independents, as assumed by the Black – Scholes model, the correlation coefficient would be very close to zero indicating

3.1 INTRODUCTION In this chapter, the focus is on the methodology used in the study. It include the data collection, data source, variables, research design, theoretical research framework, sampling design, test consideration for data analysis, hypotheses statement and conclusion. 3.2 DATA COLLECTION Data collection involves the process of gathering information and data either from primary or secondary data. In this study only secondary data is used. 3.2.1 Secondary Data Secondary data refers to

he world economy is based on the natural resources that are the raw materials and the world need this resources is increasing rapidly. raw materials can be traded and their size and quality have been standardized to be the commodities. there are three types of commodities, energy commodities, metal commodities and commodities. commodities markets have been created before 150 years in the united states and commodities trading had existed in Japan before more than a 1,000 years.Agricultural commodities

CHAPTER FOUR MODELING OF FORECASTING INFLATION IN NEPAL 4.1Introduction Inflation is a burning economic problem in the developing countries like Nepal that brings adverse effects like loss of purchasing power of national currency, leading to the aggravation of social conditions and living standards. This also leads to uncertainty making domestic and foreign investors reluctant to invest in the economy. Additionally, inflation broadens the country’s terms of trade causing domestic goods and services

Many investors when making a decision regarding investing in a other country take into account certain factors which may play a very important role or may affect their future returns. Standard economics theory suggests that over the long run, profits or returns should rise in line with the economy/ economic growth, which is also the view point of many investors when making a decision. Although the long run research and studies conducted by different economists gives a very different picture of

Our question is, “Does the level of education you receive affect the amount of income you will earn?” Currently, it is said that you need at least a college degree to earn a decent income. This question is often important because in todays society, the amount of money one makes is important to the quality in which one wishes to live. By looking at data we have found through our research it seems as if the higher your level of schooling, reaching anywhere from a high school diploma to a phD, generally
