Multivariate Synthetic Control Method Using Time Series

Three generalizations of the synthetic control method (which has already an implementation in package 'Synth') are implemented: first, 'MSCMT' allows for using multiple outcome variables, second, time series can be supplied as economic predictors, and third, a well-defined cross-validation approach can be used. Much effort has been taken to make the implementation as stable as possible (including edge cases) without losing computational efficiency. A detailed description of the main algorithms is given in Becker and Klößner (2018) .


News

Changes in version 1.3.1 (2018-01-04)

Changes

  • minor documentation update (references)

Bug fixes

  • some fixes/increased robustness for edge cases (e.g. single predictor)

  • progress bar fixed (thereby eliminating compiler warnings)

Changes in version 1.3.0 (2017-08-17)

New features

  • cross validation is now supported by function mscmt, see the corresponding documentation.

Changes

  • point size is now settable in ggplot.mscmt.

  • lp's in ill-conditioned problems are now tackled with the help of various lp solvers to improve robustness. Packages Rglpk and lpSolveAPI are required now.

Bug fixes

  • 'no sunny donors' case fixed.

  • gamma-factors fixed.

  • some small bug fixes in ggplot.mscmt.

Changes in version 1.2.0 (2017-01-30)

New features

  • automatic repeated estimation with different outer optimizers and random seeds, optionally on a cluster.

Changes

  • reasonable default parameters and documentation for outer optimizers have been added.

  • improved cluster support: (malfunctioning) load balancing with parLapplyLB replaced by load balancing via clusterApplyLB.

Bug fixes

  • fixed special treatment of 'one sunny donor' case.

Changes in version 1.1.0 (2016-11-29)

New features

  • newly supported outer optimizer "none" to implant 'artificial' solutions (fixed w and optionally fixed v).

  • many new outer optimizers are now supported, more documentation will follow.

  • function compare() for comparison of estimation results, including corresponding updates for print.mscmt and ggplot.mscmt.

Changes

  • names of agg.fns (component of mscmt results) are now set automatically.

  • user-defined agg.fns are now automatically exported to the cluster.

  • changed default optimizer to DEoptC.

  • predictor weights are not printed any more as verbose output in estimations.

  • some packages were moved from "Imports" to "Suggests".

  • number of calls to inner optimizer is now counted for benchmarking purposes.

  • package startup message added.

Bug fixes

  • objective function weights alpha/beta/gamma are now treated correctly.

  • calls to the lp solver are now more robust.

  • some typos in vignettes have been corrected.

  • all data had to be sorted chronologically, this is now optional.

  • improveSynth reported wrong 'True' W*(V) if W*(V) was not optimal.

Changes in version 1.0.0 (2016-07-25)

New features

  • first public release of this package.
