This dissertation studies the least squares estimator of a trend parameter in a simple linear regression model with multiple changepoints when the changepoint times are known. The error component in the model is allowed to be autocorrelated. The least squares estimator of the trend and the variance of the trend estimator are derived. Consistency and asymptotic normality of the trend estimator a...

It is very important that the results of statistical analysis are understandable. Therefore, while reporting analysis, some effect size measures should be given along with P-value. In this study, measure Eta-Squared, Epsilon Squared and Omega-Squared were compared in terms their performance (bias) simple multiple linear regression models. Results simulation runs showed estimates quite unbiased ...
