simple linear regression equation for sample

y and education is independent variable i.e. Now we take an example to understand this equation well, for instance, income is dependent variable i.e. Look at the above equation, y is dependent variable, β 0 is regression constant, β 1 is the coefficient that quantifies the effect of independent variable on dependent variable, x 1 sample data for independent variable and ε is the error of estimation. The population formula of simple linear regression model is given below: – population formula of simple linear regression Let’s briefly explain them with the help of example.Įquation, y is dependent variable which is a function of independent variables

Regression, there are two types of variables:ĭependent variables are those which we are going to predict while independent variables are predictors.

nominal, and one plus independent variables i.e. nominal or dichotomous Multinomial Regression ordinal, and one plus independent variables i.e. interval or ratio or dichotomous Ordinal Regression dichotomous, and two plus independent variables i.e.

interval or ratio or dichotomous Logistic Linear Regression interval or ratio, and two plus independent variables i.e. interval or ratio or dichotomous Multiple Linear Regression interval or ratio ,and one independent variable i.e. Some types of linear regression analysis Simple Linear Regression
