WebNov 11, 2024 · So my question is: How can I use cluster-based permutation statistics when I have the heatmaps and connectivity maps, without starting from the time domain signals? A simple approach that I have tried, is to compare the mean levels of the data, though this is a big reduction of information, because it reduces the matrices into just 1 … Web1) Run LMM for each data point using: pupil ~ bgcolor + congruency + bgcolor*congruency + (1 sub) 2) Collect t-values 3) Identify clusters 4) Generate null distribution by shuffling labels of bgcolor and congruency within each subject. Include permutations where no cluster was above threshold and assign them 0 cluster mass.

WebJan 30, 2024 · The effect size after averaging the data in the largest cluster is the one that most closely relates to the statistical inference that was done here using a cluster-based permutation test. However, it is very difficult to report the precise details of the cluster due to its ragged shape.
WebJul 3, 2024 · Using cluster-based permutation testing, we found that, during a time period of 256 to 530 ms after cue onset, RSA similarity values were higher for representations of identical cues as compared to different cues (cluster-based permutation testing: t cluster = 799.66, P = 0.019; Fig. 2, B and C). This significant difference allowed us to define ...

WebCluster-level permutation tests for event-related fields are performed by the function ft_timelockstatistics. This function takes as its input arguments a configuration structure (cfg) and two or more data structures. These data structures must be produced by ft_timelockanalysis or ft_timelockgrandaverage, which all operate on preprocessed data. men\u0027s americana fashionWebJan 27, 2014 · - Bootstrap_compare_cluster.m that estimates the 95% bootstrap confidence interval of B measure; - PermTest_cluster_compare.m that performs a permutation test on B measure.
