Quantile - Study guides, Class notes & Summaries

For assessing the normality assumption of the ANOVA model, we can only use the quantile-quantile normal plot of the residuals. - False In simple linear regression models, we loose three degrees of freedom because of the estimation of the three model parameters, B0, B1, and Sigma^2? - False In evaluating a simple linear model - there is a direct relationship between the coefficient of determination and the correlation between the predicting and response variables. Assuming that the data are...

ISYE 6414 Midterm Prep Questions and Answers Graded A+ 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 multi...
