The documentation for the latest release is at

The documentation for the development version is at Recent improvements are highlighted in the release notes https://www.statsmodels.org/stable/release/ In this lecture, you'll learn how to run your first multiple linear regression model. This lesson will be more of a code-along, where you'll walk through a multiple linear regression model using both statsmodels and scikit-learn. Recall the initial regression model presented.

It determines a line of best fit by minimizing the sum of squares of the errors between the models predictions and the actual data. In algebra and statistics classes, this is often limited to the simple 2 variable case of $y=mx+b$, but this process can be generalized to use multiple predictive variables. The code below reiterates the steps you've seen before: For now, let's simplify the model and only inlude 'acc', 'horse' and the three 'orig' categories in our final data. It's time to apply the StatsModels skills from the previous lesson! In this lab , you'll explore a slightly more complex example to study the impact of spending on different advertising channels on total sales.

In this lab, you'll work with the "Advertising Dataset", which is a very popular dataset for studying simple regression. The dataset is available on Kaggle, but we have downloaded it for you. It is available in this repository as advertising.csv. You'll use this dataset to answer this question: Which advertising channel has the strongest relationship with sales volume, and can be used to model and predict the sales? Based on what you have seen so far, describe the contents of this dataset.

Remember that our business problem is asking us to build a model that predicts sales. Every record in our dataset shows the advertising budget spend on TV, newspaper, and radio campaigns as well as a target variable, sales. A comprehensive repository showing how to perform Linear Regressions with StatsModels. Designed as a learning resource for Python Data Science and Machine Learning enthusiasts. In this lab, you'll practice fitting a multiple linear regression model on the Ames Housing dataset! The Ames Housing dataset is a newer (2011) replacement for the classic Boston Housing dataset.

Each record represents a residential property sale in Ames, Iowa. It contains many different potential predictors and the target variable is SalePrice. We will focus specifically on a subset of the overall dataset. These features are: For each feature in the subset, create a scatter plot that shows the feature on the x-axis and SalePrice on the y-axis. Set the dependent variable (y) to be the SalePrice, then choose one of the features shown in the subset above to be the baseline independent variable (X).

Let’s explore linear regression using a familiar example dataset of student grades. Our goal will be to train a model to predict a student’s grade given the number of hours they have studied. In this implementation, we will use the statsmodels package to achieve this. Exploring relationship between variables: Identifying the dependent and independent variables: When using statsmodels, the documentation instructs us to manually add a column of ones (to help the model perform calculations related to the y-intercept):

Linear models with independently and identically distributed errors, and for errors with heteroscedasticity or autocorrelation. This module allows estimation by ordinary least squares (OLS), weighted least squares (WLS), generalized least squares (GLS), and feasible generalized least squares with autocorrelated AR(p) errors. See Module Reference for commands and arguments. \(Y = X\beta + \epsilon\), where \(\epsilon\sim N\left(0,\Sigma\right).\) Depending on the properties of \(\Sigma\), we have currently four classes available: GLS : generalized least squares for arbitrary covariance \(\Sigma\)
