Utilities for converting unstructured electronic prescribing instructions into structured medication data. Extracts drug dose, units, daily dosing frequency and intervals from English-language prescriptions. Based on Karystianis et al. (2015) <doi:10.1186/s12911-016-0255-x>.

Performs sensitivity analysis for the sharp null, attributable effects, and weak nulls in matched studies with continuous exposures and binary or continuous outcomes as described in Zhang, Small, Heng (2024) <doi:10.48550/arXiv.2401.06909> and Zhang, Heng (2024) <doi:10.48550/arXiv.2409.12848>. Two of the functions require installation of the 'Gurobi' optimizer. Please see <https://docs.gurobi.com/current/#refman/ins_the_r_package.html> for guidance.

Provides a parallel backend for the %dopar% function using
        the snow package of Tierney, Rossini, Li, and Sevcikova.

Constructs dynamic optimal shrinkage estimators for the weights of the global 
  minimum variance portfolio which are reconstructed at given reallocation 
  points as derived in Bodnar, Parolya, and Thorsén (2021) (<arXiv:2106.02131>).
  Two dynamic shrinkage estimators are available in this package. One using 
  overlapping samples while the other use nonoverlapping samples.

Provides high-level functions to compute estimates (means,
    proportions, totals, ratios and quantiles) for complex survey designs,
    with automatic classification of statistical reliability, between-year
    significance tests and standardised report generation in 'Excel' format
    (via 'openxlsx'). It was developed for the Social Observatory
    ('Observatorio Social') of the Chilean Ministry of Social Development
    and implements its data-quality criteria, but it can be applied to any
    complex-survey design (for example the Chilean 'CASEN' household survey,
    included as example data). The reliability criteria follow Division
    Observatorio Social (2023)
