Would appreciate a potted summary of the complex output for FFT in Excel and any general remarks about FFTs. However, the magnitude of the dominant frequency in the FFT is at least 10 times higher than the input - I don't understand why this is, but there must be a good reason why.

The tutorial explains the basics of regression analysis and shows how to do linear regression in Excel with Analysis ToolPak and formulas.

the discrete fourier transform, the fast fourier transform, taylor series. The complex numbers (FFT data) produced from Excel on this data I have converted using (x^2+y^2)^0.5 where x+yi is the format of the complex number this apparantly yields the 'magnitudes of the FFT'. Multiple Linear Regression Example You illustrates XLMinerвЂ™s Multiple Linear Regression method using the Boston Housing in multivariate analysis). The data analysis toolpak is not installed with the standard excel setup.

My input - acceleration - data is sinusoidal in nature (also only a single frequency) the maximum amplitude being 0.5g. Since there is very little documentation on this function within Excel, could someone cast light on the following:

Excel has produced a set of FFT data which is a series of complex numbers. With the XLMiner Analysis ToolPak Add-on, you can easily perform statistical analyses of the same types available in the Analysis ToolPak add-in that has been part of Microsoft Excel for over 20 years, and has been featured in large numbers of textbooks, videos, statistics courses and the like. The function is sampled at N times, tk kt where k0,1,2.,N1.1. Suppose that a physical process is represented by the function of time,ht( ). I have performed a Fast Fourier Transform on a set of acceleration data within Excel using the Analysis Toolpak -> Data Analysis -> Fourier Analysis (thanks, Michael!). Debevec FebruThe discrete Fourier transform may be used to identify periodic structures in time series data. If you are prompted that the Analysis ToolPak is not currently installed on your computer, click Yes.

If Analysis ToolPak is not listed in the Add-Ins available box, click Browse to locate it. In the Add-Ins box, check the Analysis ToolPak check box, and then click OK. This is semi-related to an earlier thread. If you're using Excel for Mac, in the file menu go to Tools > Excel Add-ins.
