KyPlot™ 5.0 Free

Data Analysis and Visualization Software

KyPlot is a software package for data analysis and visualization.
You can read an article about KyPlot from  here .
The followings are main functionalities of KyPlot.

New functionality in Version 5.0.3

Added "Maximum Likelihood for Y=F(X;A)" in "Function Fit".

For the regression problem: Y=F(X;A) + error with the probability (density) function P(X;A) for Y is given, parameters, A1, A2 , … are estimated by maximum likelihood method.

By using Cauchy distribution, or more generally Pearson family of distributions, or Huber function for P(X;A), this can be used for robust regression. For details, see the Pages 3 and 4 in the sample file "Robust.kyp".

Drawing

•It is possible to draw a line, a B-spline curve, an ellipse, a polygon, a text, etc., grouping, and aligning with the mouse only. You can also set the size and position of the shape numerically to create an accurate picture.

•In the editing of text, you can set it freely like a word processor software such as superscript, subscript, and line spacing, and you can write a formula.

 

•You can import or export diagrams and graphs in the following formats:

Windows meta file (wmf), Enhanced meta file (emf), Windows bitmap (bmp), JPEG (jpg), TIFF (tif), Portable Network Graphics (png), Photoshop (psd), Encapsulated PostScript (eps, only raster format)
