Testing the significance of the slope of the regression line
Testing the significance of the slope of the regression line We now show how to test the value of the slope of the regression line. Basic Approach By Property 1 of One Sample Hypothesis Testing for Correlation, under certain conditions, the test statistic t has the property But by Property 1 of Method of Least Squares and by Definition […]
Fitness of Regression Line Test
Fit of the Regression Line Basic Concepts On this webpage, we show how to test the following null hypothesis: H0: the regression line doesn’t capture the relationship between the variables If we reject the null hypothesis it means that the line is a good fit for the data. We now express the null hypothesis in […]
Regression Analysis Using Excel
Regression Analysis The goal of regression analysis is to describe the relationship between two variables based on observed data and to predict the value of the dependent variable based on the value of the independent variable. Even though we can make such predictions, this doesn’t imply that we can claim any causal relationship between the […]
Method of Least Squares Using Excel
Method of Least Squares In Correlation we study the linear correlation between two random variables x and y. We now look at the line in the xy plane that best fits the data (x1, y1), …, (xn, yn). Recall that the equation for a straight line is y = bx + a, where b = the slope of the line a = y-intercept, i.e. […]
