Prediction Accuracy Measures for a Nonlinear Model and for Right-Censored Time-to-Event Data
非线性模型与右删失事件时间数据的预测准确度量
This article develops a pair of new prediction summary measures for a nonlinear prediction function with right-censored time-to-event data. The first measure, defined as the proportion of explained variance by a linearly corrected prediction function, quantifies the potential predictive power of the nonlinear prediction function. The second measure, defined as the proportion of explained prediction error by its corrected prediction function, gauges the closeness of the…
