abstract: 'Implements four support vector regression (SVR) models derived from a unified
  mathematical framework for percentage-error loss functions: epsilon-SVR minimizing
  the mean absolute percentage error (MAPE), its symmetric kernel extension, least-squares
  SVR (LS-SVR) minimizing the root mean square percentage error (RMSPE), and its symmetric
  counterpart. All models require strictly positive targets. The epsilon-SVR models
  are solved via a built-in sequential minimal optimization (SMO) algorithm (with
  ''osqp'' available as an optional alternative backend) and the LS-SVR models via
  a linear system (base R). See Benavides-Herrera et al. (2026) <https://doi.org/10.3390/math14101679>
  for the mathematical derivations.'
