How to analyse the data in a series

Once you have data in a series, you can analyse either the Y data or the x data alone, or compare the x and y values.

X or Y Statistics

The series properties Xstats and Ystats give the same information about the x and y data, including Mean, median, quartiles and quintiles, SD, skew and others

Comparison between X and Y

The series property CompStats gives a comparison between the x and y values, includin g the Pearson correlation, the p Value and the results of the regression. Some of the values returned by Compstats depend on the kind of regression chosen.

Regressions

Several kinds of regression and curve fitting are available. Although I have called them all regression, technically only the first 3 are, and the other 3 are only curve fitting techniques.You can choose between Linear regression, Passing / Bablok regression, Quadratic regression, and Distance Weighted Least Squares fitting, Spline fitting, and Running Average Approximation.
