- Sums of 1-parameter functions, such as convoluted exponentials in fast
- Optional global analysis of up to about 50 data sets with the same
decay constants (e.g., multi-wavelength sets);
- Optional robust correction for response function in fast fluorescence
decay using standards .
- Running on a wide variety of computers.
- fully automatic: no starting estimates needed for the number of
components or for their parameters;
- modified Gauss-Newton least squares, with intensive searches from many
starting points to find the global optimum;
- optional spline approximation of model functions [2,3] for faster
analyses (probably unnecessary with current computers).
