# regression coefficient calculator

I designed this web site and wrote all the lessons, formulas and calculators. The line of best fit is described by the equation ŷ = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). Enter two data sets and this calculator will find the equation of the regression line and corelation coefficient. Simply add the X values for which you wish to generate an estimate into the Estimate box below (either one value per line or as a comma delimited list). This web site owner is mathematician Miloš Petrović. 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). It also produces the scatter plot with the line of best fit. Welcome to MathPortal. Correlation and regression calculator Enter two data sets and this calculator will find the equation of the regression line and corelation coefficient. This calculator will compute the 99%, 95%, and 90% confidence intervals for a regression coefficient, given the value of the regression coefficient, the standard error of the regression coefficient, the number of predictors in the model, and the total sample size. All rights reserved. This calculator will compute the 99%, 95%, and 90% confidence intervals for a regression coefficient, given the value of the regression coefficient, the standard error of the regression coefficient, the number of predictors in the model, and the total sample size.Please enter the necessary parameter values, and then click 'Calculate'. For the case of a simple linear regression, the correlation coefficient may range from -1 to 1. Consider the following set of points: \${(-3 , -4), \, (2 , 3), \, (7 , 11)}\$. There is a large difference between the two extrapolations of number of confirmed cases projecting to … Enter all known values of X and Y into the form below and click the "Calculate" button to calculate the linear regression equation. This simple multiple linear regression calculator uses the least squares method to find the line of best fit for data comprising two independent X values and one dependent Y value, allowing you to estimate the value of a dependent variable (Y) from two given independent (or explanatory) variables (X1 and X2). Calculator: Regression Coefficient Confidence Interval, Regression Coefficient Confidence Interval Calculator. m = The slope of the regression line a = The intercept point of the regression line and the y axis. For example, if you wanted to generate a line of best fit for the association between height and shoe size, allowing you to predict shoe size on the basis of a person's height, then height would be your independent variable and shoe size your dependent variable). 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) … This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X. Note: If you just want to generate the regression equation that describes the line of best fit, leave the box below blank. Just now, with info available the power regression gives a slightly higher r than the exponential equation. The values of \$X\$ and their corresponding values of \$Y\$ are shown in the table below: Please tell me how can I make this better.
