    methods such as OLS. This is because one of the underlying assumptions of OLS is that is a constant and is the basis for measuring volatility. A GARCH(1,1) model is able to model this feature because it estimates a model for , which allows the variance to change over time. C) To test for ARCH effects in the return series, we would start by estimating the return equation using least squares. We would then square the residuals from the return equation and regress the squared residuals on its lags

    CHAPTER 4 DATA ANALYSIS Coefficient Correlation Analysis The first analysis is by using Ordinary Least Square (OLS) test to measure the relationship of entire variables. The test is to find the function which most closely approximates the data. Thus, in general terms, it is an approach to fitting a model to the observed data. The details information regarding the variables is shown in table 4.1 and table 4.2 shows the least square test that measures all the variables. Variables Description LGP
