gseries 3.0.2

(G-Series 3.0 in R)

• Minor changes to comply with the CRAN requirements following the second submission process:
  • New package title (DESCRIPTION).
  • Return values added for function aliases (aliases.R).
  • Operator <<- replaced with environment specific assignments (for more predictive behaviour).

gseries 3.0.1

(G-Series 3.0 in R)

• Bug fix in tsbalancing() to avoid altering the R session’s error option (getOption("error")) after execution.

• Validation of class “data.frame” input objects in (relevant) utility functions for coherence with the core functions.

• Updated description of the function arguments regarding the expected class of input objects.

• Minor changes to comply with the CRAN requirements following the initial submission process.

gseries 3.0.0

(G-Series 3.0 in R)

• Initial release of G-Series in R (package gseries).

• New functionality (stock_benchmarking()) designed for benchmarking stocks using a cubic spline interpolation approach.

• Improvements to the already existing functionalities:

  • Benchmarking (benchmarking()):
    • new options allowing proportional benchmarking (lambda != 0) in presence of negative values in the input data;
    • a flat indicator series of all zeros is now allowed with additive benchmarking (lambda = 0).
  • Raking (tsrasking()):
    • optional alternative handling of negative values in the input data (same handling as tsbalancing());
    • helper function (tsraking_driver()) to simplify the reconciliation of several periods in a single function call.
  • Balancing (tsbalancing()):
    • customizable solving sequence (multiple attempts at solving the problem as opposed to a single attempt);
    • improved solution validation process with more information (output data frames) available to help troubleshooting invalid solutions;
    • optional input data validation only process (without attempting to solve the problem, i.e., resolve the discrepancies, if any).

• New utility functions to help using the core functions, e.g.;

  • for producing benchmarking plots;
  • for converting reconciliation problem metadata (tsrasking() to tsbalancing());
  • for manipulating time series data (prepare or convert the input and output data objects).
