Manual analysis of human high-resolution colonic manometry data is time consuming, non-standardized and subject to laboratory bias. In this article we present a technique for spectral analysis and statistical inference of quasiperiodic spatiotemporal signals recorded during colonic manometry procedures. Spectral analysis is achieved by computing the continuous wavelet transform and cross-wavelet transform of these signals. Statistical inference is achieved by modeling the resulting time…

High‐resolution impedance manometry characterizes the functional role of distal colonic motility in gas transit
The application of high‐resolution impedance manometry in the human colon in vivo is described to characterize distal colonic motility and gas transit after a meal and after intraluminal gas insufflation into the sigmoid colon.
Altered anal slow‐wave pressure activity in low anterior resection syndrome: short case series in two independent specialist centres provide new mechanistic insights
Whether there are differences in anal canal slow‐wave pressure activity in LARS patients and healthy individuals is assessed.
Post‐operative colonic manometry in children with Hirschsprung disease: A systematic review
Manometry may be used to investigate the gastrointestinal motility patterns of this population of children following surgical repair of Hirschsprung disease.


Efficient Bayesian hierarchical functional data analysis with basis function approximations using Gaussian-Wishart processes.
This work proposes a novel Bayesian method based on the Bayesian hierarchical model with a Gaussian-Wishart process prior and basis function representations that can efficiently smooth and estimate high-dimensional functional data, providing one way to resolve the curse of dimensionality for Bayesian functional data analysis with Gaussia-W Wishart processes.
Fully automated analysis of colonic manometry recordings
Developing a computer program for fully automated analysis of all hitherto described colonic motility patterns is feasible and overall wave prevalences markedly decreased, but the distribution over the various motor patterns was preserved.
Spectral Analysis of Replicated Biomedical Time Series
SUMMARY Standard methods of spectral analysis are adapted to the interpretation of biomedical time series data with replication across subjects. The methodology is applied to two sets of data
Wavelet-based functional mixed models.
New methodology is presented that generalizes the linear mixed model to the functional mixed model framework, with model fitting done by using a Bayesian wavelet-based approach, which is flexible, allowing functions of arbitrary form and the full range of fixed effects structures and between-curve covariance structures that are available in the Mixed model framework.
Smoothing and Mean–Covariance Estimation of Functional Data with a Bayesian Hierarchical Model
Simulations and real data analysis demonstrate that the proposed Bayesian approach achieves better smoothing accuracy and comparable mean-covariance estimation results, and can successfully retain the systematic patterns in the functional observations that are usually neglected by the existing functional data analyses based on individual-curve smoothing.
Bayesian analysis of mass spectrometry proteomic data using wavelet-based functional mixed models.
The recently developed Bayesian wavelet-based functional mixed model methodology is applied to analyze MALDI-TOF mass spectrometry proteomic data to identify spectral regions that are differentially expressed across experimental conditions, in a way that takes both statistical and clinical significance into account and controls the Bayesian false discovery rate to a prespecified level.
Toward a diagnostic toolkit for linear models with Gaussian-process distributed random effects.
This article proposes tools for understanding how data determine estimates in linear mixed models, using a spectral basis approximation to the GP under which the restricted likelihood is formally identical to the likelihood for a gamma-errors GLM with identity link.
Application of the cross wavelet transform and wavelet coherence to geophysical time series
It is demonstrated how phase angle statistics can be used to gain confidence in causal relation- ships and test mechanistic models of physical relationships between the time series and Monte Carlo methods are used to assess the statistical significance against red noise backgrounds.
Wavelet-Based Nonparametric Modeling of Hierarchical Functions in Colon Carcinogenesis
New methods for analyzing the data from an experiment using rodent models to investigate the effect of type of dietary fat on O6-methylguanine-DNA-methyltransferase (MGMT), an important biomarker in early colon carcinogenesis, are developed.
A Novel Method for Electrophysiological Analysis of EMG Signals Using MesaClip
An algorithm developed for a continuous wavelet transform that enables the filtering out of frequencies contributing to the shapes of action potentials (spikes), whilst retaining the frequencies that encode the periodicity of spike trains is presented.
