As promised last week, today: What is the #OLS method? 👉🧵

Questions about #statistics? Then feel free to post them in the thread! 👏

1️⃣ #Residual
For each x-value there is a point on the regression line - the predicted value ŷ. The distance between this and the actual value y is called the residual.

2️⃣ #OLS
The "best fitting line" is found by minimizing exactly this distance. OLS minimizes the sum of squared residuals.

This week: What is a #regression? 🤔⬇️

1️⃣ #Regression
statistical method to describe the #relationship between at least 2 variables. It only establishes #correlation, not #causality. A regression yields an #estimate, not an exact #prediction.

2️⃣ #Example
the higher the temperature, the more #icecream is sold. So there is a positive and linear relationship between the two #variables. The difference between a point and the line is called the #residual.

This week: What are #mediator and #moderator? 🧐

1️⃣ #Mediators
are variables that mediate the relationship between two other variables. The independent variable has an effect on the mediator, and the mediator in turn has an effect on the dependent variable.
2️⃣ #Moderators
are variables that affect the relationship between two other variables. They can change the direction and strength of the effect of the independent variable on the dependent variable.
