This chapter investigates methods for analyzing cross-sectional data, i.e., data which are represented in matrix form, where each row represents one process instance. The analysis methods can be grouped into supervised learning methods, also known as predictive analysis, and unsupervised learning. ...
Causal inference in complex systems has been largely promoted by the proposal of some advanced temporal causation models. However, temporal models have serious limitations when time series data are not available or present insignificant variations, which
We provide a general class of tests for correlation in time series, spatial, spatio-temporal and cross-sectional data. We motivate our focus by reviewing how computational and theoretical difficulties of point estimation mount, as one moves from regularly-spaced time series data, through forms of ...
Here, we develop an intuitive model that can be fit with cross-sectional data with censored survival information to generate individual aging trajectories that include both healthandsurvival. Our model is adapted from previous work modeling human aging with stochastic dynamics on a complex network16,...

An extension of component analysis to longitudinal or cross-sectional data is presented. In this method, components are derived under the restriction of invariant and/or stationary compositing weights. Optimal compositing weights are found numerically. The method can be generalized to allow differential ...
Ideally, vulnerability at the household level would be estimated with panel data of sufficient length and richness. However, such data are rare, especially in poor, developing economies. We argue in this paper that despite the limitations of purely cross-sectional data, an analysis of these data...
