%description
Estimation of the required sample size to validate a risk model for binary
outcomes, based on the sample size equations proposed by Pavlou et al.
(2021) <doi:10.1177/09622802211007522>. For precision-based sample size
calculations, the user is required to enter the anticipated values of the
C-statistic and outcome prevalence, which can be obtained from a previous
study. The user also needs to specify the required precision (standard
error) for the C-statistic, the calibration slope and the calibration in
the large. The calculations are valid under the assumption of marginal
normality for the distribution of the linear predictor.
