Online Linear Regression Calculator This page allows you to compute the equation for the line of best fit from a set of bivariate data: Enter the bivariate x,y data in the text box. x is the independent variable and y is the dependent variable. Data can be entered in two ways: x ...
The least squares regression line can be found in the other way. LetˉXandˉYbe the corresponding sample means andsXandsYbe sample deviations of these variables. The least squares regression line is the lineˆy=a+bxforb=sXYsYsX,a=ˉY−bˉXand correlation coefficientrXYbetweenXandY. ...
Linear Regression Calculator Enter numbers for Independent Variable (X) separated by commas, spaces, or line breaks[example]: Enter numbers for Dependent Variable (Y) separated by commas, spaces, or line breaks[example]: Precision: Embed Linear Regression Calculator Widget ...
Linear Regression Calculator is an online tool that helps to determine the equation of the best-fitted line for the given data set using the least-squares method.
Linear regression is one of the most popular modeling techniques because, in addition to explaining the relationship between variables (like correlation), it also gives an equation that can be used to predict the value of a response variable based on a value of the predictor variable. ...

The formula for the correlation r is presented, explained, and the nine steps for computing a correlation are explained using a calculator example. Then, the Excel commands for computing a correlation are presented along with the Excel steps needed to create a chart summarizing the relationship ...
This simple linear regression calculator uses the least squares method to find the line of best fit for a set of paired data, allowing you to estimate the value of a dependent variable (Y) from a given independent variable (X). The line of best fit is described by the equation ŷ = ...
Compare this to other methods like correlation, which can tell you the strength of the relationship between the variables, but is not helpful in estimating point estimates of the actual values for the response. What is the difference between the variables in regression?
Linear regression calculator with unlimited predictors and transformations. Draw charts, validate assumptions (normality, multicollinearity, homoscedasticity, power).
