The discriminant performance of models was measured using the time-dependent area under the curve (AUC) using the SurvivalROC R package 32.
A concordance index (C-index) for the time-dependent area under the ROC curve (AUC (t)) was calculated to assess model predictive performance, varying from C-index = 0.5 (no predictive power) to C-index = 1 (perfect prediction).
The time-dependent areas under the receiver operating characteristic curve demonstrated that the WFA+-M2BP assay predicted the development of HCC with higher diagnostic accuracy than AFP.
The predictive power of the models was assessed as time dependent Area Under the Receiver Operatic Characteristic Curves (AUC t)) and summarized by the concordance index (C-index) [ 17].
In order to combat noise and create acoustic environments of high quality, it is of utmost importance to be able to predict the time dependent sound field in such areas.
The structural level, revealed by the location of the local maxima of the current source density distribution, describes the time dependent network of activated brain areas.
The time dependent function for the transient evolution of specific surface area was generated from measured mercury porosimetry data.
The time-dependent normalized area was quantified by dividing the difference between the cell area at time t and the initial spread area (i.e., Ainitial − A t)) by the difference in area between the first and last time points (i.e., Ainitial − Afinal).
The time-dependent normalized area was quantified by dividing the difference between the cell area at time t and the initial spread area (i.e., A t) − Ainitial) by the difference in area between the first and last time points (i.e., Afinal − Ainitial).
We evaluate the prediction performance using a time-dependent area under the curve (AUC) [ 15].
From analysis of the time-dependent extended area using Avrami analysis, analysis of the near-neighbor distribution, and the correlation between the island size and the spatial distribution, we conclude that island growth is controlled by surface diffusion-mediated lateral growth.
