Am I right in assuming you want to do some regression on time series? If so, the following article should shed some light on the potential pitfalls when using regular regressions and why some special methods smut be used. See "Time Series Regression" at http://www.csulb.edu/~msaintg/ppa696/696regs.htm#TIME%20SERIES%20REGRESSION Moreover, the package _Time Series_, "A Fully Integrated Environment for Time-Dependent Data Analysis", might be well suited for your needs. See http://www.wolfram.com/products/applications/timeseries/ Finally, the following notebook might be of some help: see "Time Series Functions and Examples", freely available at http://library.wolfram.com/infocenter/MathSource/5079/ Hope this helps (and that I am not off topic), Jean-Marc
