What is The Use of Tilde in R? Tilde (~) Operator
Tilde operator is used in statistical formulas where we need to define the relationship between a dependent variable and an independent variable.
Variables on the left-hand side of tilde are considered as dependent variable and variables on right-hand-side of tilde is are called independent variables.
> Regression_Model_relationship <- qa(y~ n1 + n2 + n3)
In the above equation, we have the object Regression_Model_relationship that stores the formula for linear regression and created by qa and y. So, qa and y are on the left-hand side of tilde are dependent variables, and n1, n2, and n3 are independent variables.
Examples of Tilde Operator in R
> Regression_Data_relationship <- data.frame(n1, n2, n3, y) > Regression_Model__relationship_New < - qa(y~ . , data = Regression_Data_relationship)
