Sample-Specific Root Causal Inference with Latent Variables
, 2022 Root causal analysis seeks to identify the set of initial perturbations that induce an unwanted outcome. In prior work, we defined sample-specific root causes of disease using exogenous error terms that predict a diagnosis in a structural equation model. We rigorously quantified predictivity using Shapley values.

Testing the Assumptions Behind the Use of Importance Sampling [PDF]
Importance sampling is used in many aspects of modern econometrics to approximate unsolvable integrals. Its reliable use requires the sampler to possess a variance, for this guarantees a square root speed of convergence and asymptotic normality of the ...

An early warning system for multivariate time series with sparse and non-uniform sampling [PDF]
, 1962 In this paper we propose a new early warning test statistic, the ratio of deviations (RoD), which is defined to be the root mean squared of successive differences divided by the standard deviation.

Temporal sampling of root exudates using coated blade-SPME for decoding plant–pathogen interactions
Frontiers in Plant ScienceRoot exudates shape the rhizosphere and mediate plant–microbe interactions, yet traditional sampling techniques often disturb the natural environment. Here, we present the use of coated blade-solid-phase microextraction (CB-SPME) method for passive, non ...

Sampling Citrus Fibrous Roots and Tylenchulus semipenetrans.
Journal of nematology, 2011 Sampling precision was investigated for Tylenchulus semipenetrans juveniles and males in soil and females from roots and for citrus fibrous root mass density. For the case of two composite samples of 15 cores each, counts of juvenile and male nematodes were estimated to be within 40% of mu, at P < 0.06 (alpha) in orchards where x > 1,500 nematodes/100 ...

Characterization of Root System Architectures from Field Root Sampling Methods
, 2020 $\textbf{Background and objectives:}$ The root system architecture (RSA) of a plant determines the plant’s ability to capture resources efficiently from the soil and directly linked to plant performance. The development and distribution of plant’s root systems are determined by the soil and surrounding environmental conditions.
