Adjusted r squared - Study guides, Class notes & Summaries

A/B Test - 1) An experiment that compares the value of a dependent variable (ex = likelihood that a website visitor purchases an item) across two different groups (control group and treatment group). Members of each group must be RANDOMLY SELECTED to ensure that the only difference between the groups is the "MANIPULATED" independent variable (ex = size of the font on two otherwise identical websites)...a hypothesis test that tests whether the means of the dependent variable are the same across t...

Least Square Elimination (LSE) cannot be applied to GLM models. - False - it is applicable but does not use data distribution information fully. In multiple linear regression with idd and equal variance, the least squares estimation of regression coefficients are always unbiased. - True - the least squares estimates are BLUE (Best Linear Unbiased Estimates) in multiple linear regression. Maximum Likelihood Estimation is not applicable for simple linear regression and multiple linear regres...

Adjusted R-Squared Correct Answer-A goodness-of-fit measure in multiple regression analysis that penalises additional explanatory variables by using a degrees of freedom adjustment in estimating the error variance. Alternative Hypothesis Correct Answer-The hypothesis against which the null hypothesis is tested. AR(l) Serial Correlation Correct Answer-The errors in a time series regression model follow an AR(l) model. Attenuation Bias Correct Answer-Bias in an estimator that is always to...

In a greenhouse experiment with several predictors, the response variable is the number of seeds that germinate out of 60 that are planted with different treatment combinations. A Poisson regression model is most appropriate for modeling this data - False - poisson regression models rate or count data. The R-squared and adjusted R-squared are not appropriate model comparisons for non linear regression but are for linear regression models. - TRUE - The underlying assumption of R-squared cal...
