Endogeneity in High Dimensions.
Most papers on high-dimensional statistics are based on the assumption that none of the regressors are correlated with the regression error, namely, they are exogenous. Yet, endogeneity can arise incidentally from a large pool of regressors in a high-dimensional regression. This causes the inconsistency of the penalized least-squares method and possible false scientific discoveries. A necessary...
متن کاملEndogeneity in Probit Response Models
In this paper, we look at conventional methods for removing endogeneity bias in regression models, including the linear model and the probit model. The usual Heckman two-step procedure should not be used in the probit model: from a theoretical perspective, this procedure is unsatisfactory, and likelihood methods are superior. However, serious numerical problems occur when standard software pack...
متن کاملEndogeneity in Marketing Decision Models
T are many critical concerns (including the accounting for endogeneity) when one is properly estimating response functions. However, it is sometimes (certainly not always) better to leave some variables exogenous when building mathematical models intended to help decision makers. The exogenous variables allow the decision maker to better adapt the mathematical model to different situations and ...
متن کاملEndogeneity in Residential Location Models
The development of models to understand the behavior of an Urban Transportation System (UTS) as a whole is crucial, not only for the evaluation and exploration of policies to manage the level of pollution and congestion in the cities, but also for solving problems such as the efficient provision of utilities, infrastructure and schools. UTS can be viewed as the result of the interaction of many...
