This necessity is motivated by applying fundamental notions of statistical hypotheses testing to neural network research. Minimum requirements concerning statistical evaluation are developed and the appropriate statistical techniques are introduced. Articles from two leading neural network journals are exa...

At its simplest, voxel-based morphometry (VBM) involves a voxel-wise comparison of the local concentration of gray matter between two groups of subjects.

INTRODUCTION Some have suggested the quality of reporting of network meta-analyses (a technique used to synthesize information to compare multiple interventions) is sub-optimal. We sought to review information addressing this claim. OBJECTIVE To conduct an overview of existing evaluations of quality of reporting in network meta-analyses and indirect treatment comparisons, and to compile a lis...
