WebApr 11, 2024 · I agree I am misunderstanfing a fundamental concept. I thought the lower and upper confidence bounds produced during the fitting of the linear model (y_int above) reflected the uncertainty of the model predictions at the new points (x).This uncertainty, I assumed, was due to the uncertainty of the parameter estimates (alpha, beta) which is … WebStudents will take notes about draw scatterplots, find the line of regression from a dataset, and use the regression line to make a prediction.This flipbook contains everything your students need for linear regression. Only linear regression is shown in this flipbook. These notes are designed to be used for an Algebra 2 class.
