A structural equation formulation for general quasi-periodic Gaussian processes
Unnati Nigam, Radhendushka Srivastava, Faezeh Marzbanrad +1
This paper introduces a structural equation formulation that gives rise to a new family of quasi-periodic Gaussian processes, useful to process a broad class of natural and physiol…
A semi-parametric model for assessing the effect of temperature on ice accumulation rate from Antarctic ice core data
Radhendushka Srivastava, Debasis Sengupta
In this paper, we present a semiparametric model for describing the effect of temperature on Antarctic ice accumulation on a paleoclimatic time scale. The model is motivated by sha…
Feature Sensitive Curve Registration by Kernel Matching
Dibyendu Bhaumik, Radhendushka Srivastava, Debasis Sengupta
In this paper, we argue that the problem of registering two sets of functional data, where the underlying mean function has sharp features, is not properly addressed by methods des…
Feature Sensitive and Automated Curve Registration
Dibyendu Bhaumik, Radhendushka Srivastava, Debasis Sengupta
Given two sets of functional data having a common underlying mean function but different degrees of distortion in time measurements, we provide a method of estimating the time tran…
RAPTT: An Exact Two-Sample Test in High Dimensions Using Random Projections
Radhendushka Srivastava, Ping Li, David Ruppert
In high dimensions, the classical Hotelling's test tends to have low power or becomes undefined due to singularity of the sample covariance matrix. In this paper, this proble…
