Calculator with step by step explanations to find equation of the regression line and correlation coefficient.
Linear regression is used to model the relationship between two variables and estimate the value of a response by using a line-of-best-fit. This calculator is built for simple linear regression, where only one predictor variable (X) and one response (Y) are used.
The linear regression calculator calculates the best fitting equation and the ANOVA table. The calculator draws the linear regression line (line fit plot) and the residual plot. Tests the linear model assumptions: residual normality, power, outliers. Generates step by step calculation.
On DATAtab you have the possibility to use the linear regression calculator online. The calculator allows you to model the linear relationship between two or more variables online. The regression statistics calculator therefore provides you with all relevant statistical values for your data.
In simple linear regression, the starting point is the estimated regression equation: ŷ = b 0 + b 1 x. It provides a mathematical relationship between the dependent variable (y) and the independent variable (x). Furthermore, it can be used to predict the value of y for a given value of x.
The linear regression calculator, formula, work with steps, rela world problems and practice problems would be very useful for grade school students (K-12 education) to learn what is linear regression in statistics and probability, and how to find the line of best fit for two variables.
Linear Regression Calculator. Instructions: Perform a regression analysis by using the Linear Regression Calculator , where the regression equation will be found and a detailed report of the calculations will be provided, along with a scatter plot. All you have to do is type your X and Y data.
