Improved data handling

Load, transform and analyze in one line. Simple to use formula string notation supports:

  • Categorical and dummy variables
  • Data transformations (ln, exp and more)
  • SAS and Stata datasets

Generalized Method of Moments (GMM)

New GAUSS 18 GMM procedures estimate parameters from custom user specified moment equations or analytic instrumental variables estimates using one step, two-step, iterative, or continuously updating GMM.


Graphics updates

Convey insights from your data with modern, professional images.

  • 30+ built-in color palettes, and custom palettes
  • Programmatic canvas sizing
  • Added 2-D plot flexibility and options

New functions to increase productivity

Uncover data insights quicker with new tools for searching matrices and string arrays, reorganizing, merging, and much more!

Speed improvements

• Chained concatenation operations 2-4x faster
• X’Y for vector-vector case 15%-600% faster
• Descriptive statistics and OLS 15-30% faster for medium to large matrices

New mathematical functions

besselk computes the modified Bessel function of the second kind; useful for the negative inverse gaussian distribution.
rndRayleigh to compute Rayleigh distributed random numbers.
gmmFit and gmmFitIV for estimation using the generalized method of moments.
cdfTruncNorm, pdfTruncNorm, cdfLogNorm and pdfLogNorm.
• Optional mu, and sigma inputs for cdfn and pdfn
