Understanding Logistic Regression Using a Simple Example

WebJun 18, 2024 · R², p-value and F-statistic. As you can see, the R² is much higher than that of simple linear regression, with a value of 0.897! Also, the F-statistic is 570.3. This is much greater than 1, and since our data set if fairly small (only 200 data points), it demonstrates that there is a strong relationship between ad spending and sales. WebJul 11, 2024 · The likelihood-ratio test on a model fit by maximum likelihood, (for example, a logistic regression or another generalized linear model), is a counterpart to the F test on a linear regression model. Both allow for testing the overall model against the null model (in R, outcome ~ 1 ), as in your question, and generally for testing nested models ... WebFeb 19, 2024 · The formula for a simple linear regression is: y is the predicted value of the dependent variable ( y) for any given value of the independent variable ( x ). B0 is the intercept, the predicted value of y when the x is 0.
