This calculator finds the least-squares fit to a list of tow-column data as a exponential function with polynomial exponent up to a specified order.

The size of input data is limited to 1024 points or less to converve system resources. The input format must be strictly followed to have a correct data parsing.

Inputs   Help
Numerical data only. Input data must have "," between columns and ";" between rows. [Space], [Tab], and [Enter] will be ignored.
