“…To accommodate this effect, Bandi and Russell (2005b) incorporated leads and lags in their estimator. This is an old solution in the literature to overcome the nonsynchronicity of observations (see Cohen et al, 1983;Dimson, 1979;Scholes and Williams, 1977). For two given assets, Bandi and Russell's (2005c) lead-lag estimator with U lags and L leads is given by…”

“…• We do not account for a potential asynchronous trading problem for the index versus the modeled stock; given our data, unreported results on a correction methodology by Cohen et al (1983) do not show a substantial impact on the parameter estimates of the SMM.…”
“…XX wieku powstało kilka metod korekty obciążenia estymatora parametru beta. Do najbardziej znanych i najczęściej stosowanych w praktyce należą klasyczne modele oraz procedury empiryczne przedstawione w pracach: [Scholes, Williams 1977;Dimson 1979;Cohen et al 1983;Hawawini 1983;Fowler et al 1989]. Jako metodę korekty estymatora parametru beta stosuje się też metodę bayesowską z pracy [Vasicek 1973], jednak podstawowym problemem w praktycznym zastosowaniu tej metody jest trudność w ustaleniu przekonań a priori badacza odnośnie do wartości parametru beta.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
