Assuming that the data are normally distributed, under the simple linear model, the estimated variance has the following sampling distribution: - Chi-squared with n-2 degrees of freedom. The fitted values are defined as? - The regression line with parameters replaced with the estimated regression coefficients.

We can assess the constant variance assumption in linear regression by plotting the residuals vs. fitted values. - True If one confidence interval in the pairwise comparison in ANOVA includes zero, we conclude that the two corresponding means are plausibly equal. - True The assumption of normality is not required in linear regression to make inference on the regression coefficients. - False (Explanation: is required) We cannot estimate a multiple linear regression model if the predicting v...

T/F The expected value of a random walk is dependent on time. Note: Make sure you understand what a random walk is! Think of the drunken man. - False. X_t = X_(t-1) + W_t, where W_t ~ Normal(0,V). T/F A moving average process is a linear process. - True. T/F If X_t is a stationary time series, then -Xt must be a non-stationary time series. - False. Taking the negative of the series does nothing to affect trend, variance, or add autocorrelation, and thus the process remains stationary. T/F...
