TableCurve 2D v.5. 1. 2005
Now you can save time with TableCurve 2D - a linear and non-linear curve fitting program.
Tocr v.0.2.0
Convert head-curve data files with this tool. tocr can convert the head-curve data file from ECAT HR+ (*.r) or HRRT (*.hc) to count-rate (.cr) file format, that is suitable for correction of time-delay between blood/plasma and tissue TACs.
Dft2dat v.1.2.5
Convert PET tracer time-activity curve data with this program. dft2dat help you convert PET tracer time-activity curve data in DFT format (1) to pure numeric data (with no header information or title lines),
Dftsmo v.0.0.4
Smooth time-activity curve data with this utility. dftsmo is a smoothing of time-activity curve data using the method of Peter A Gorry.Usage: dftsmo [Options] Options: -o= By default 2 (binomial
Dft2rfit v.0.1.0
DFT time-activity curve data conversion made easy. dft2rfit can convert DFT time-activity curve data into RFIT 4.4 compatible ROI or BLOOD format. DFT is a multipurpose data file format for regional tissue time-activity curves, blood or plasma TACs
Visual Fitting v.2.5.0
Math tool for linear, nonlinear curve fitting and surface fitting, curve and surface can be created.
CurvFit v.6.11
A curve fitting program: Lorentzian, Sine, Exponential & Power series are available models to match your data. A Lorentzian series is recommended for real data especially for multiple peaked data. Another improved productivity example.
DataFitting v.1.7.22
DataFitting is a powerful statistical analysis program that performs linear and nonlinear regression analysis (i.e. curve fitting).
EASY-FIT ModelDesign v.5 13
Proceeding from given experimental data, i.e., observation times and measurements, the minimum least squares distances of measured data from a fitting criterion are computed, which depends on the solution of the dynamic system.
Regression Analysis - CurveFitter v.4.5.6
CurveFitter program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions.
