Web26. sep 2024. · @user575406's solution is also fine and acceptable but in case the OP would still like to express the Distributed Lag Regression Model as a formula, then here are two ways to do it - In Method 1, I'm simply expressing the lagged variable using a pandas transformation function and in Method 2, I'm invoking a custom python function to … WebFor this example, we will create a minimal dataset, and explore fitting a simple linear model fit to it, using OLS. In this case, we will be using numpy for measuring least squares. Note that for real datasets, this is unlikely to be how you apply models, since it will usually be more practical to use scikit-learn or statsmodels to manage all the components of model …
