What’s new?

StatFree version 8.4.1.0 of 24.09.2016 - Transpose within the Procedure Creator included.

StatFree version 8.4.0.0 of 19.06.2016 – The new command <Fix Cycle N | within the Procedure Creator interpolates the selected columns to have a fixed number of data lines. The command is particularly relevant for attractor analysis. The window for creating graphs of measurement data is enhanced. In addition the unwanted phase shift when iterating is removed.

StatFree version 8.3.0.2 of 27.01.2016 – Merging of the two data sets vertically added.

StatFree version 8.3.0.0 of 16.01.2016 - A function called log(Variable) is included. It returns the last number within the column of the specified Variable. From within the Procedure Operator selected or all log(Variable) values can be recorded.

StatFree version 8.2.0.9 of 26.11.2015 - Two minor bugs (not updating header & wrongly added line feeds while loading an equation) within Function Analysis removed.

StatFree version 8.2.0.8 of 14.11.2015 - Compiled for optimal use with Microsoft's Windows 10.

StatFree version 8.2.0.7 of 03.10.2015 - The ACS (AutoCycle Setting) parameter can take values from 1 to 40, which is equivalent to the quantile setting in %. The old setting 1, 2, 3, 4 corresponds to 10, 20, 30, 40 of the new setting.

StatFree version 8.2.0.3 of 20.09.2015 - The order to calculate substitutions changed to A9, A8, …, A1, A0. This can alter the way an equation with substitutions must be written.

StatFree version 8.2.0.0 of 22.08.2015 - Includes the new functions 2D-AutoCycle and 3D-AutoCycle to calculate attractor attributes of cyclic processes automatically.

StatFree version 8.1.0.3 of 05.10.2014 - The text sensitive help works for the 32 bit as well as for the 64 bit version of StatFree. There is just one file - StatFreeInstall.exe, which will install StatFree version 32 bit or 64 bit depending on your Windows operation system.

StatFree version 8.1.0.0 of 26.09.2014 - The creation of the "empirical attractor" for cyclic 2D- and 3D-motion can be "Phase ordered" beside "Time ordered" as previously introduced. As a default the "Equation directory" can be set to be the "Working directory". 

StatFree version 8.0.0.0 of 17.10.2013 - Newly included are the Procedures Creator (automatic progression builder), the Procedure Operator (automatized mass analysis tool), equation path setting, and the relative addressing. 

StatFree version 8.0.0.0 beta of 21.04.2013 - available as 32 & 64 bit versions. The 64 bit version does not display context sensitive help (Sorry, this is caused by a compiler bug. Unfortunately, I can't do anything but wait for a bug fix myself).

StatFree version 7.0.3.0 of 01.07.2012 – Wavelet Multiresolution Analysis / time-frequency interpretation re-defined.

StatFree version 7.0.2.0 of 11.02.2012 – Indicator for undefined symbols or variables within the various equation editors included.

StatFree version 7.0.0.0 (05.01.2012) - Technical upgrade, compiled for use with Windows 7 (32 bit). Substantial extension of Function Analysis (3 instead of 1 function, their derivatives, and integrals displayable) and Iterations can be performed to calculate (strange) attractors etc. New display and manipulation tools are integrated within Wavelet Multiresolution Analysis. 

StatFree version 6.0.0.0 of 09.01.2011 – Major technical overhaul and new functionality. New window Function Analysis included. Simpler writing of expressions like exponents as (expression 1)^(expression 2), ln() etc. Compiled for Window 7 but does work with Windows XP and Vista as well.

StatFree version 3.4.4.0 of 16.09.2006 – The newly included functions – Enl(x) and Cut(x) – let you enlarge and cut a data set for use with FFT and iFFT. The setting of Case Numbering and Variable Numbering within the two Data Editors is stored within the StatFree.ini file, so that the chosen options remain till the next setting.

StatFree version 3.4.3.0 of 27.08.2006 – The newly included function – Spline(x) – let you approximate missing data (empty fields) by generating a cubic spline.

StatFree version 3.3.0.0 of 18.05.2006 – A Fourier transform can be initiated from within any of the two grids. Depending on the options set additional columns displaying frequency [Hz], real part of the transform, imaginary part of the transform, absolute of the transform and/or phase angle are added. Instead of the logistic equation a function calculating the trend line is included. The logistic equation might be calculated using the equation generator. The tutorials don’t show up separately since they are integrated within the help file.

StatFree version 3.2.1.0 of 19.02.2006 – Equation builder included and a field for equation names to each graphic window. The equation builder is an additional window that can be opened separately. It can be zoomed and therefore has the capacity to host huge equations and offers ten fields for substitutions.

Trouble Shooting 

If StatFree opens with an error message and closes immediately you need to erase the StatFree.ini file in the program directory (it is located in ...\VietenDynamics\StatFree or in another directory depending on your settings). Afterward, StatFree opens with the initial settings.

If after a longer calculation the Add Variable(s) window does not close, save the data, and start the application newly.

If a whole graphic screen (2D-graphs or 3D-graphs) appears in one (line) color, switch back the Line Width to a number between 1 and 9.

StatFree does adjust to your PC's DPI setting (Dot Per Inch). However, if you experience distortion of the elements of the various windows change the DPI to 100%. You can adjusted the DPI parameter within Window's System Control display setting.
