SEATTLE, WA � September 6, 2007 � Insightful Corporation (NASDAQ: IFUL), a leading provider of predictive analytics and reporting solutions, announced today the immediate release of three time series analysis software packages via Insightful�s Comprehensive S-PLUS� Archive Network (CSAN).

Simply put, the term "fractal" means that certain statistical measures of data are invariant upon rescaling the data. However, the measures are quite different for stochastic and deterministic models (e.g., invariance in distributional properties in the former and invariance in space-filling properties in the latter). Researchers have used stochastic fractal models to interpret observed data from real-world systems such as cardio-dynamics (heart rate variability), turbulence, atmospheric and climate changes, atomic clock deviations, sea ice measurements and blood flow.

Insightful has released the following time series packages via CSAN at csan.insightful.com:

• FRACTAL: stochastic fractal time series and nonlinear modeling
• WMTSA: wavelet methods for time series analysis
• SAPA: spectral analysis for physical applications
