The least-squares method minimizes the sum of squares of deviation of data points from the line to calculate the best fit line for observed data in linear regression. a is the y-intercept (i.e., the value of y when x=0).In regression analysis, we refer to the dependent variables as the response or predicted variables, and we also call the independent variables the explanatory variables or predictors.Ī linear regression line has an equation of the kind: Y= a + bX Linear refers to the fact that we use a line to fit our data. Linear Regression models have a relationship between dependent and independent variables by fitting a linear equation to the observed data. If there is only one independent variable, then it is a simple linear regression if some independent variables are more than one, then it is multiple linear regression. In linear regression, we use independent variables to predict the value of a dependent variable. Linear regression is a statistical technique/method used to study the relationship between two continuous quantitative variables.
