Table 5 Number of times each candidate update model was selected by the closed testing procedure when the sliding window equals 1, 2, 4, or 8 quarters and the update interval equals 1 quarter
From: Comparison of dynamic updating strategies for clinical prediction models
Candidate update model in closed testing procedure | Sliding window | |||
