XLSTAT 2006

Addinsoft announces the availability of XLSTAT 2006, a true revolution in the small world of statistical add-ins for Excel. XLSTAT 2006 has been completely thought and written using new programming languages to make XLSTAT 2006 faster, even more reliable, easier to use, and open.

Here is a non-exhaustive list of what's new in XLSTAT 2006:

General software improvements

  • new dialog boxes: tabs allow to manage options for the computations and for the display of results.
  • two new languages, portuguese and japanese.
  • computations are now done in C++ allowing a significant increase in speed.
  • possibility in many functions to use transposed tables to circumvent the limitation of Excel to 256 columns.
  • possibility to use XLSTAT functions programmatically in VBA.
  • possibility to access the XLSTAT C++ functions programmatically from any environment.
  • more detailed help file.
  • only one software needs to be downloaded (the unique exe file includes all the modules).

XLSTAT-Pro

  1. Preparing data:
    • Distribution sampling: new distributions
  2. Describing data:
    • histograms: several histograms can be superimposed, and theoretical distributions can be plotted over the histograms.
    • new tool: multicolinearity statistics (Tolerances, VIFs).
    • new options in similarity/dissimilarity matrices.
  3. Visualizing data:
    • strip-plots.
    • more options for box plots.
    • new function to automatically modify a chart so that it is orthonormal (aspect ratio = 1).
    • new tool to merge two charts (for example, two curves available in 2 different charts).
    • more options for Easylabels.
    • new tool to modify the labels position.
  4. Analyzing data:
    • Factor analysis: polychoric correlations, better charts, new rotation options, maximum likelihood option.
    • PCA: polychoric correlations, better charts, new rotation options. New biplots.
    • CA/ MCA: new methods for subset analysis. Non symetrical correspondence analysis.
    • Discriminant analysis: better handling of multicolinearity cases, possiblity to include qualitative variables, stepwise options, cross-validation
    • Hierarchical clustering: dendrograms can now ne modified, groups can be shown with different colors.
    • K-Means : new clustering criteria.
  5. Modeling data:
    • Distribution fitting: new distributions.
    • Linear regression: better handling of multicolinearity cases, improved stepwise options.
    • ANOVA/ANCOVA: simpler interface for the multiple comparisons tests and better management of interactions.
    • Logistic regression: better handling of multicolinearity cases, PCR option, stepwise options, and multiple comparisons are possible when categorical variables have been selected.
  6. Association tests:
    • Correlation maps can now be displayed after correlation tests.
    • New association measures have been added.
    • Mantel test has been improved.
  7. Parametric tests:
    • possibility to run tests on several variables in one run.
    • easier management of alternative hypotheses.
  8. Nonparametric tests:
    • exact tests are now possible for most methods.
  9. Tools:
    • easier to use DataFlagger.
    • tool to remove hidden sheets with possibility to select only some of them.
    • tool to find the min and/or the max in a sheet.

XLSTAT-3DPlot

  • New interface with many new options

XLSTAT-MX

  • PREFMAP: simplified interface, possibility to add contour plots
  • GPA: permutation tests, new options to display results

XLSTAT-Time

  • Possibility to use dates to display the results, and confidence intervals in ARIMA can be used on long time series.

XLSTAT-Life

  • Comparison tests after Kaplan-Meier analyses and life table analyses can now be applied to more than two groups.

XLSTAT-Pivot

  • simplified interface, quicker computations.
