R help - Dec 2016 - New R package on CRAN: productivity (0.1.0)

Dear R users,


I am happy to announce that the R package 'productivity: Indices of 
Productivity Using Data Envelopment Analysis' is now available on CRAN 
(https://cran.r-project.org/package=productivity).

Productivity allows computing various transitive measures of 
productivity and profitability, in both levels and changes.
In addition to the classic Malmquist productivity index, 'productivity' 
also contains the multiplicatively complete and transitive F?re-Primont 
and Lowe indices.

All estimations are based on the nonparametric Data Envelopment Analysis 
(DEA) and several assumptions regarding returns to scale are available 
(i.e. CRS, VRS, NIRS, NDRS).

Besides, the package allows parallel computing.

I would certainly appreciate feedback, comments and suggestions from 
more experienced packagers and R users at 
https://r-forge.r-project.org/projects/productivity/


Best regards,

Yann

Dear R users,


I am happy to announce that the R package 'sfadv: Advanced Methods for 
Stochastic Frontier Analysis' is now available on CRAN 
(https://CRAN.R-project.org/package=sfadv).

This package allows stochastic frontier analysis with advanced methods.
Particularly it implements newly developped method proposed by Latruffe 
et al. (2017) <doi:10.1093/ajae/aaw077> considering stochastic frontier 
analysis with technical inefficiency effects and endogeneity of one input.

Best regards,

Yann
