Adaptive Cluster Thresholding with Spatial Activation Guarantees Using All-resolutions Inference
Xu Chen, Jelle J. Goeman, Thijmen J. P. Krebs +2
Classical cluster inference is hampered by the spatial specificity paradox. Given the null-hypothesis of no active voxels, the alternative hypothesis states that there is at least…
Joint Quantile Regression for Spatial Data
Xu Chen, Surya T. Tokdar
Linear quantile regression is a powerful tool to investigate how predictors may affect a response heterogeneously across different quantile levels. Unfortunately, existing approach…
Paired-move multiple-try stochastic search for Bayesian variable selection
Xu Chen, Shaan Qamar, Surya T. Tokdar
Variable selection is a key issue when analyzing high-dimensional data. The explosion of data with large sample sizes and dimensionality brings new challenges to this problem in bo…
A weighted edge-count two-sample test for multivariate and object data
Hao Chen, Xu Chen, Yi Su
Two-sample tests for multivariate data and non-Euclidean data are widely used in many fields. Parametric tests are mostly restrained to certain types of data that meets the assumpt…
