mvpa2.misc.stats.DSMatrix

class mvpa2.misc.stats.DSMatrix(data_vectors, metric='spearman')

DSMatrix allows for the creation of dissilimarity matrices using arbitrary distance metrics.

Initialize DSMatrix

Parameters :

data_vectors : ndarray

m x n collection of vectors, where m is the number of exemplars and n is the number of features per exemplar

metric : string

Distance metric to use (e.g., ‘euclidean’, ‘spearman’, ‘pearson’, ‘confusion’)
