Improvements have been made in the following areas:
Improved data handling
Load, transform and analyze in one line. Simple to use formula string notation supports:
- NEW formula strings
- Read SAS and STATA datasets
- Improved Handling of Large Datasets
General Method of Moments (GMM)
New Graphics Functionality
- New Color Palette Options and Defaults
- Control graph canvas size programmatically
- Other new features
New Functions to Increase Productivity
Speed Improvements
- Chained concatenation operations 2-4x faster
- X'Y for vector-vector case 15%-600% faster
- Inverse incomplete gamma function up to 10x faster
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
- Array support for erf, erfc, erfcinv, erfc, pdfn, power op.
