最近看了一篇论文。文中说The significance of group differences in each region was estimated by distributional approximations from the theory of random Gaussian fields, and significance levels were set at p<0.05 (corrected for multiple comparisons). 这样校正的,请问他用的是哪种校正呢?
我们通常用的校正是不是只有FWE是用了随机场理论呢?
他后面文章中写道:For patient data, individual r value maps were analyzed with a random effect one-sample t test to identify voxels showing a significant positive or negative correlation to the seed time series,with correlations thresholded using a family-wise error correction at p<0.05.
这个一定是用FWE嘛,因为他family-wise error correction,可是第一段那个校正他用的是什么呢?

我觉得是的。 spm是利用随机场理论计算有效自由度。 然后
这个问题对我来说太难了,但似乎是一个比较普遍的问题,请来防
