%description
Provides a flexible, simulation-based toolkit for exploring how much data
are needed to develop reliable prediction models. It works by repeatedly
generating data, fitting models, and evaluating performance to show how
sample size affects predictive accuracy, calibration, and overfitting. The
package supports continuous, binary, and time-to-event outcomes and can be
used with both regression-based modelling approaches and machine-learning
methods. It is designed to help researchers plan studies, assess
feasibility, and build more robust and generalisable models. The methods
are described in Olaniran et al. (2026) <doi:10.1186/s12874-026-02935-9>
and Shamsutdinova et al. (2026) <doi:10.48550/arXiv.2602.23507>.
