Probabilistic properties of a nonlinear ARMA process with markov switching
, 2018 We consider a nonlinear autoregressive moving average (ARMA) process with Markov switching and find sufficient conditions for strict stationarity, geometric ergodicity, and the existence of moments of the process with respect to the stationary ...

From Groups to Individuals: How Identifiability Reduces Biased Meta‐Perceptions and Polarization
Journal of Applied Social Psychology, EarlyView.ABSTRACT Political polarization reflects not only people's attitudes toward rival groups but also their meta‐perceptions—beliefs about how one's group is viewed by the opposing side. These second‐order beliefs are often negatively biased and exaggerated (Lees and Cikara 2020), reinforcing mistrust and perceived division.

Experimental Investigation of Hydraulic Fracturing in Vertical and Horizontal Perforated Boreholes
, 2013 In this study, scaled hydraulic fracturing tests are conducted on 10 and 15 cm cubical mortar samples. The importance of scaled fracturing tests should be highlighted as the results of non-field-like fracturing tests cannot be compared with or used for ...

Scalable Likelihood Inference for Student-t Copula Count Time Series
StatsCount time series often exhibit extremal dependence that may not be adequately captured by Gaussian copula models. We develop a likelihood-based framework for count-valued time series using Student-t copulas with latent ARMA dependence.
