QuData Y(X) Finder Allows to fit empirical data (xi, yi) with the most suitable analytical function y=y(x). To analyze your data, copy the column of values of the independent variable x from a text file or electronic table and paste it into the left editing field. Copy the column of values of the dependent variable y(x) from a text file or electronic table and paste it into the editing field on the right. Each value of y(x) must correspond to respective value of independent variable x. Clicking the button for a function you will get the corresponding fit's coefficients and parameters of error for data approximation with this function (deviation of data from analytical function).
