When doing linear regression, it is important to include right right variables in your model. Multiple regression differs from simple linear regression in that more than one explanatory variable is used in the model. Master variable selection in multiple regression with our concise guide! Dive into the art and science of choosing the right predictors for your statistical models. This video is perfect for data science enthusiasts, statisticians, and researchers looking to enhance their model's accuracy and efficiency. Learn about key concepts such as multicollinearity, Adjusted R-squared, stepwise regression, forward selection, and backward elimination. In this video you'll learn about using R programming for your regression analysis. R is a powerful tool when it comes to statistical analysis. Whether you're working on predictive analytics, machine learning projects, or academic research, our expert insights will help you make informed decisions on which variables to include in your multiple regression model. Boost your data analysis skills today and ensure your models are both powerful and precise!

Hi thanks for the video! Would you expect that going forward vs backwards would always produce the same model? I assume the answer is no (otherwise they wouldn't both need to exist), and it seems like you started to explain it a bit at the end, but I'm not sure I understand the difference. Further, it seems like if a linear model is the right model, and the fwd/bwd options exist, you would always want to create your lm's in this way since it will produce the most explanatory model. Is that a reasonable conclusion? Thanks in advance!
