In panel (h), it is also shown that B t) is non-observable.
We compare two cases: one in which capital is non-observable and non-verifiable and one in which it is observable and verifiable.
The idea behind the PSM approach is to find control observations (that is, non-invaded households) having initial observable characteristics similar to the invaded households, to serve as valid surrogates for the missing counterfactuals.
This methodology allows me to observe outcomes for returnees and non-migrants that are similar in both observable and non-observable characteristics, except for one important dimension migration status.
Global finite-time observers are designed for a class of nonlinear systems that are uniformly observable and possibly non-Lipschitz.
In this paper, we extend the semi-global finite-time observers design to a broader class of single-output systems that are uniformly observable and possibly non-Lipschitz.
Additionally, XOR observability is defined for languages that are not inference observable but are distributed observable.
Things like colors, size, shapes, numbers -- all of the things that are completely observable.
We control for these variables and incorporate fixed effects to control for non-observable components that are not related to wellbeing such as the different size of migration across different pairs of countries and other potential idiosyncratic components, as well as time effects to allow for comparison across different years.
"Anxiety and depression tend to be characterized by distressing internal experiences that are not always observable to others," she added.
