Linear regression is used to study the linear relationship between a dependent variable Y (blood pressure) and one or more independent variables X (age, weight, sex). The dependent variable Y must be continuous, while the independent variables may be either continuous (age), binary (sex), or categorical (social status).

Frequently Asked Questions

What is the meaning of r in linear regression?

R - Linear Regression. The other variable is called response variable whose value is derived from the predictor variable. In Linear Regression these two variables are related through an equation, where exponent (power) of both these variables is 1. Mathematically a linear relationship represents a straight line when plotted as a graph.

What is simple linear regression?

Simple linear regression fits a straight line to the data points that best characterizes the relationship between the dependent ( Y) variable and the independent ( X) variable, with the y -axis intercept ( b0 ), and the regression coefficient being the slope ( b1) of this line:

What are predictor and response variables in linear regression?

One of these variable is called predictor variable whose value is gathered through experiments. The other variable is called response variable whose value is derived from the predictor variable. In Linear Regression these two variables are related through an equation, where exponent (power) of both these variables is 1.

What is univariable linear regression?

Univariable linear regression studies the linear relationship between the dependent variable Y and a single independent variable X. The linear regression model describes the dependent variable with a straight line that is defined by the equation Y = a + b × X, where a is the y-intersect of the line, and b is its slope.
