In this post, I will explain Linear Regression in simple terms. It could be considered as a Linear Regression for dummies post, however, I’ve never really liked that expression. In the Machine…
What is the difference between simple linear regression and multiple linear regression? Once you’ve decided that your study is a good fit for a linear model, the choice between the two simply comes down to how many predictor variables you include. Just one? Simple linear. More than that?
Linear regression calculates the estimators of the regression coefficients or simply the predicted weights, denoted with 𝑏₀, 𝑏₁, …, 𝑏ᵣ. These estimators define the estimated regression function 𝑓(𝐱) = 𝑏₀ + 𝑏₁𝑥₁ + ⋯ + 𝑏ᵣ𝑥ᵣ. This function shoul...

Simple linear regression is used to model the relationship between two continuous variables. Often, the objective is to predict the value of an output variable based on the value of an input variable.
Simple linear regression: reminder Simple linear regression is an asymmetric procedure in which: one of the variable is considered the response or the variable to be explained. It is also called dependent variable, and is represented on the yy-axis the other variable is the explanatory or also ...
If the relationship displayed in your scatterplot is not linear, you will have to either run a non-linear regression analysis or "transform" your data, which you can do using Stata. Assumption #4: There should be no significant outliers. Outliers are simply single data points within your dat...
The F-test statistic for joint significance of the slope coefficients of a regression is routinely reported in regression outputs, along with other key statistics such as R² and t-ratio values. The…
Why Would One Use a Multiple Regression Over a Simple OLS Regression? A dependent variable is rarely explained by only one variable. In such cases, an analyst uses multiple regression, which attempts to explain a dependent variable using more than one independent variable. The model, however, as...
Ineconometrics,linear regressionis an often-used method of generating linear relationships to explain various phenomena. It is commonly used in extrapolating events from the past to make forecasts for the future. Not all relationships are linear, however. Some data describe relationships that are curve...
