Multiple testing corrections, nonparametric methods, and random field theory
نویسنده
چکیده
I provide a selective review of the literature on the multiple testing problem in fMRI. By drawing connections with the older modalities, PET in particular, and how software implementations have tracked (or lagged behind) theoretical developments, my narrative aims to give the methodological researcher a historical perspective on this important aspect of fMRI data analysis.

Nonparametric permutation tests for functional neuroimaging: a primer with examples.
Requiring only minimal assumptions for validity, nonparametric permutation testing provides a flexible and intuitive methodology for the statistical analysis of data from functional neuroimaging experiments, at some computational expense. Introduced into the functional neuroimaging literature by Holmes et al. ([1996]: J Cereb Blood Flow Metab 16:7-22), the permutation approach readily accounts ...
متن کاملNonparametric Estimation of Spatial Risk for a Mean Nonstationary Random Field}
The common methods for spatial risk estimation are investigated for a stationary random field. Because of simplifying, lets distribution is known, and parametric variogram for the random field are considered. In this paper, we study a nonparametric spatial method for spatial risk. In this method, we model the random field trend by a local linear estimator, and through bias-corrected residuals, ...
متن کاملBayesian Nonparametric Approach to Multiple Testing
Motivated by the problems in genomics, astronomy and some other emerging fields, multiple hypothesis testing has come to the forefront of statistical research in the recent years. In the context of multiple testing, new error measures such as the false discovery rate (FDR) occupy important roles comparable to the role of type I error in classical hypothesis testing. Assuming that a random mecha...
متن کاملForest Stand Types Classification Using Tree-Based Algorithms and SPOT-HRG Data
Forest types mapping, is one of the most necessary elements in the forest management and silviculture treatments. Traditional methods such as field surveys are almost time-consuming and cost-intensive. Improvements in remote sensing data sources and classification –estimation methods are preparing new opportunities for obtaining more accurate forest biophysical attributes maps. This research co...
متن کامل- e STAGGERING ENTRY , RANDOM WITHDRAWAL AND PROGRESS IVE CENSORING SCHEMES
SUMMARY. In a life testing experiment (or a clinical trial), for staggering entry of units (including some batch arrival models), some nonparametric testing procedures (based on a general class of rank statistics and weighted empirical processes) under progressive censoring schemes are considered, for some multiple regression model. Adjustments needed to incorporate dropouts are also discussed....
