   This is a demo version of a data analysis tool for the Macintosh.  Data
can be entered into a spreadsheet format and then analyzed (roots,
extrema, and integrals can be computed).  Non-linear curve fitting is
done with the Levenberg-Marquardt algorithm.  Linear methods involve a
variety of curves that can be fit to the data, including splines,
polynomials, sine curves, exponential functions, logarithmic curves, power
functions, Gauss functions, and Lorentz functions.  Monte Carlo fitting is
also implemented.  Functions and data can be plot and examined.  There are
features to manipulate the data by using transformations or sortings,
graphs can be rotated, flipped, reshaped, and smoothed.

   There is a separate program included that provides on-line help, but it
is not integrated with the program itself.

   The PowerMac version of this program was tested on a PowerMac 7100 running
sytem 7.5.1 and it ran with no difficulty.
