Sample size for external validation of a prediction model

pmvalsampsize

Sample size for external validation of a prediction model

Installation

$ pip install pmvalsampsize

Usage

pmvalsampsize computes the minimum sample size required for the external validation of an existing multivariable prediction model using the criteria proposed by Archer (2020) and Riley (2021) pmvalsampsize can currently be used to calculate the minimum sample size for the external validation of models with binary outcomes.

Continuous and survival (time-to-event) outcome model calculations are a work in progress.

from pmvalsampsize.pmvalsampsize import *

samplesize = pmvalsampsize(type="b", cstatistic=0.8, graph=True, lpbeta=(1.33, 1.75), prevalence=0.43, noprint=True) # change options to meet your requirements
plt.show()
summary(samplesize)
