The Least Squares Regression Calculator will return the slope of the line and the y-intercept. It will also generate an R-squared statistic, which evaluates how closely variation in the independent variable matches variation in the dependent variable (the outcome).
Find the least squares regression line for the data set as follows: {(2, 9), (5, 7), (8, 8), (9, 2)}. Also, work for the estimated value of y for the value of X to be 2 and 3.
Least Squares Regression is a way of finding a straight line that best fits the data, called the "Line of Best Fit". Enter your data as (x, y) pairs, and find the equation of a line that best fits the data.
Linear Regression calculator uses the least squares method to find the line of best fit for a sets of data `X` and `Y` or the linear relationship between two dataset. It estimates the value of a dependent variable `Y` from a given independent variable `X`.
Use a pre-loaded data set to start playing with our multiple regression calculator in seconds. Load data from a csv file. Use a csv (comma-separated values) file to load the data you want to analyze.
