equation slope intercept form calculator

The prediction interval for the mean value of the dependent variable. The calculator also creates the confidence interval, and the prediction interval. The prediction calculator uses the linear regrssion to predict the depdendent variable based on the independent value. How to calculate linear regression?Following the linear regression formula:ī 0 - the y-intercept, where the line crosses the y-axis.ī 1 - the slope, describes the line's direction and incline. Test the linear model significance level.Calculate the correlation between the dependent variable and the independent variables.Estimate the effect of each independent variable (X) on the dependent variable (Y).Why do you need linear regression?We may use linear regression when we want to do one of the following

The ordinary least squares method chooses the line parameters that minimize the sum of squares of the differences between the observed dependent variables (Y) and the estimated value by the linear regression (Ŷ). The linear regression model calculates the dependent variable (DV) based on the independent variables (IV, predictors). The linear regression describes the relationship between the dependent variable (Y) and the independent variables (X). There is no one way to choose the best fit ting line, the most common one is the ordinary least squares (OLS). The linear regression is the linear equation that best fits the points. It calculates the R-squared, the R, and the outliers, then testing the fit of the linear model to the data and checking the residuals' normality assumption and the priori power. It also draws: a linear regression line, a histogram, a residuals QQ-plot, a residuals x-plot, and a distribution chart. The linear regression calculator generates the linear regression equation.
