TIMP is a problem-solving environment for fitting superposition models based in the R language and environment for statistical computing and graphics.
Both TIMP and R are available as Free Software under the terms of the Free Software Foundation's GNU General Public License in source code form.
The development of TIMP is sponsored by a grant from the NWO Computational Science Programme, under the auspices of the biophysics group of the Department of Physics and Astronomy of the Vrije Universiteit Amsterdam.
