Statistics and Linear Regression: This calculator can linear regression, quadratic regression, logarithmic regression, e exponential regression, ab exponential regression, power regression and inverse regression. International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
