Webb) The explanatory variable in regression model is normally distributed. The OLS estimator is derived by a) minimizing the sum of squared residuals b) minimizing the sum of absolute residuals c) connecting the Yi corresponding to the lowest Xi observation with the Yi corresponding to the highest Xi observation Webd) When making predictions using a specific value for the explanatory variable, does the predicted value for the response variable correspond to a mean value or an individual’s value? The way regression works is that it can be either. The math for either quantity is the same, however the measure of variability (standard error) is different.

WebIntroduction: Linear Regression analysis is used to measure the association or linear relationship between two or more variables. In which one variable is (dependent or response) variable and other variables are (independent or explanatory) variables … View the full answer Transcribed image text: Websingle quantitative explanatory variable, simple linear regression is the most com-monly considered analysis method. (The “simple” part tells us we are only con-sidering a single explanatory variable.) In linear regression we usually have many different values of the explanatory variable, and we usually assume that values 頭痛 上を向くと楽 知恵袋
