title: 'llmimpute: Missing Data Imputation via Language Models and Statistics'
version: 0.1.0
abstract: 'Provides missing data imputation through two complementary engines: a large
  language model engine that communicates with the ''Anthropic'' ''Claude'' application
  programming interface for context-aware semantic imputation, and a fully self-contained
  offline engine implementing nineteen statistical and machine learning algorithms
  entirely in base R with no additional package dependencies. Offline methods include
  mean, median, mode, last observation carried forward, next observation carried backward,
  hot-deck, predictive mean matching, k-nearest neighbours, ordinary least-squares
  regression, Lasso with coordinate descent, Ridge with closed-form solution, Bayesian
  Ridge regression with evidence approximation following MacKay (1992), support vector
  regression with a radial basis function kernel, classification and regression trees,
  random forests, gradient boosting, iterative random forest imputation, principal
  component analysis imputation via iterative singular value decomposition, and nuclear-norm
  minimisation via singular value thresholding. When no API key is available the package
  automatically falls back to the offline engine, ensuring full operation in environments
  without internet access. Every imputed value is accompanied by a confidence score
  and a plain-language reasoning string, producing reproducible audit trails. The
  automatic method selector chooses the best algorithm per column based on data type,
  skewness, missingness rate, and inter-column correlations.'
