Using Subjective Expectations Data to Allow for Unobserved Heterogeneity in Hotz-Miller Estimation Strategies

Juan Pantano, Yu Zheng
2010 Social Science Research Network  
We introduce a novel approach to allow for unobserved heterogeneity in two-step structural estimation strategies for discrete choice dynamic programming models (i.e strategies that avoid full solution  ...  Of more empirical relevance, we show that our results hold when we allow these subjective future choice probabilities to be elicited in less than ideal circumstances, such as, for example, when self-reports  ...  In other words, the unobserved state k is di¤erent for the two …rms, k A 6 = k B : Therefore, di¤erences in self-reports are informative about underlying unobserved heterogeneity.  ...

Recovering individual emotional states from sparse ratings using collaborative filtering [article]

Eshin Jolly, Max Farrens, Nathan Greenstein, Hedwig Eisenbarth, Marianne Reddan, Eric Andrews, Tor D. Wager, Luke J. Chang
2021 arXiv   pre-print
Dilation kernel widths should therefore be chosen as a function of the dynamics of emotional states elicited by stimuli as well as the sparsity of the dataset.  ...  Taken together, these results suggest that CF can be an effective approach for recovering user ratings with large individual differences elicited by naturalistic dynamic stimuli [62] .  ...

Inferring The Dynamics Of "Hidden" Neurons From Electrophysiological Recordings

Valeri A. Makarov, Nazareth P. Castellanos
2008 Zenodo  
Statistical analysis of electrophysiological recordings obtained under, e.g. tactile, stimulation frequently suggests participation in the network dynamics of experimentally unobserved "hidden" neurons  ...  Such interneurons making synapses to experimentally recorded neurons may strongly alter their dynamical responses to the stimuli.  ...  INTRODUCTION Computational availability of the nervous system relies both on the properties of single neurons and importantly on their interactions, where a complex dynamical information processing unobservable  ...

BUCKLE: A model of unobserved cause learning

Christian C. Luhmann, Woo-kyoung Ahn
2007 Psychological review  
A new model of causal learning, BUCKLE (bidirectional unobserved cause learning) extends existing models of causal learning by dynamically inferring information about unobserved, alternative causes.  ...  However, information about alternative causes is frequently unavailable, rendering them unobserved.  ...  Contingencies that elicited strong causal judgments of the unobserved cause led participants to believe that the unobserved cause varied with the effect more than conditions that elicited weaker unobserved  ...
