About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators In linear regression, the "best fit" line y = mx + b satisfies the condition that the sum of the squared vertical distances between the points and the line is minimized, hence the name least squares. You can adapt the method of linear least squares regression to find an exponential regression curve y = ac x , power regression curve y = ax c , or logarithmic regression curve y = a + cLn(x). The calculator uses variables transformations, calculates the Linear equation, R, p-value, outliers and the adjusted Fisher-Pearson coefficient of skewness. After checking the residuals' normality, multicollinearity, homoscedasticity and priori power, the program interprets the results.
