| Evaluating expressions This online calculator substitutes a specific value for each variable, and performs the operations, evaluating the given expression. |
| Function approximation with regression analysis This online calculator uses several regression models for approximation of an unknown function given by a set of data points. |
| Mean, variance and standard deviation of discrete random variable This online calculator calculates the mean, variance, and standard deviation of random variables entered in the form of a value-probability table. |
| Curve fitting using unconstrained and constrained linear least squares methods This online calculator builds a regression model to fit a curve using the linear least squares method. If additional constraints on the approximating function are entered, the calculator uses Lagrange multipliers to find the solutions. |
