We introduce a novel summary statistic derived from topological data analysis, the smooth Euler characteristic transform (SECT), with well-defined inner-product structure that can be used in a wide range of functional and nonparametric modeling approaches. We show that the topological quantification of tumor MRIs are better predictors of clinical outcomes in glioblastoma multiforme (GBM) patients. SECT features alone explain more of the variance in patient survival than gene expression, volumetric, and morphometric features.
