Simple linear regression with example
WebbLinear regression with a single predictor variable is known as simple regression. In real-world applications, there is typically more than one predictor variable. Such regressions are called multiple regression. For more information, check out this post on why you should not use multiple linear regression for Key Driver Analysis with example ...

WebbWe will first apply Bayesian statistics to simple linear regression models, then generalize the results to multiple linear regression models. We will see when using the reference prior, the posterior means, posterior standard deviations, and credible intervals of the coefficients coincide with the counterparts in the frequentist ordinary least square (OLS) … WebbPython has methods for finding a relationship between data-points and to draw a line of linear regression. We will show you how to use these methods instead of going through the mathematic formula. In the example below, the x-axis represents age, and the y-axis represents speed.
