Kotlarski with a factor loading
نویسندگان
چکیده
This note extends the Kotlarski (1967) Lemma to show exactly what is identified when we allow for an unknown factor loading on common unobserved factor. That is, this completely characterizes identification of model Y = cV + U and X V W, where joint distribution known, while constant c mutually independent random variables V, U, W are unobserved. Potential applications include measurement error models panel data models.

Gust Loading Factor : New Model
Wind loads on structures under the buffeting action of wind gusts have traditionally been treated by the ‘‘gust loading factor’’ (GLF) method in most major codes and standards around the world. In this scheme, the equivalent static wind loading used for design is equal to the mean wind force multiplied by the GLF. Although the traditional GLF method ensures an accurate estimation of the displac...

متن کاملTranscription Factor Loading: Please Take My Place!
Interactions of transcription factors with chromatin are highly dynamic. Now Voss et al. (2011) demonstrate that two transcription factors with identical DNA-binding specificities do not compete for occupancy at a given DNA element, but instead, one factor can even facilitate the binding of another. This assisted loading probably involves chromatin-remodeling machines.
متن کاملTime-variant CAPM: Learning about Factor Loading
Adrian and Franzoni (2005) suggest that beta of a stock is determined by the factor loading of its unobservable long-run beta. The fundamental idea behind this model is that investors engage in a learning process of estimating this long-run beta. In this paper, a variation of this model is tested. Instead of estimating long-run beta, investors try to learn about factor loading. Given the long-r...
