Distribution of Variables In the context of ordinary least squares (OLS) regression analysis, the key variable is the regressand; in this case, ‘index’. For hypothesis testing to be valid, the error term in the model must be independently, identically normally distributed. With the regressors assumed to be constants from sample to sample, ‘index’ should also, […]
Time Series Properties of Stock Returns, Comparative Analysis of High- and Low-Frequency Data
Introduction Fama (1970) suggests that stock returns exhibit random walks through time. This means that one cannot observe any trend in the movement of returns on assets and that returns cannot be forecasted based on information about past returns. Following Fama (1965) and Mandelbrot (1963), the unconditional distribution of returns has been found to be […]

Regressions and Econometric Results
Autocorrelated error terms represent a violation of one of the assumption of the classical linear regression models. Indeed one of the major assumptions of CLRM dictates that error terms should be serially uuncorrelated, i.e. E (utut-j) = 0 for j = 1,2…. Where u is the error term and subscript t represents time. The effect […]
