资源简介：
Simulation script that evaluates the delete-two Jackknife resampling approach that was used in the partial correlation analysis of the present study. The simulation evaluates the risk of getting a false positive finding if there is no total-brain-volume-dependent bias in estimated total intracranial volume from FreeSurfer. The different parameters in the MATLAB script may be changed to see how the risk of getting a false positive finding changes. The current parameters were set to resemble those of the present study.

本仿真脚本用于评估本研究偏相关分析中所采用的双删除刀切（Jackknife）重采样方法。该仿真用于评估当通过FreeSurfer估算的颅内总体积不存在全脑体积依赖性偏倚时，出现假阳性结果的风险。可调整该MATLAB脚本中的各项参数，以探究假阳性结果风险的变化规律。当前参数设置与本研究的参数保持一致。（大小：12 KB）
