Econometrics II Lecture 2: Discrete Choice Models
... Angrist and Pischke (p.103): "...[linear regression] may generate …tted values outside the LDV boundaries. This fact bothers some researchers and has generated a lot of bad press for the linear probability model." A related problem is that, conceptually, it does not make sense to say that a probabil ...

Sparse Subspace Clustering - The Center for Imaging Science
... where Φ = [φ1 , φ2 , · · · , φm ] ∈ R is called the measurement matrix. The works of [1, 4, 7] show that, given m measurements, one can recover K-sparse signals/vectors if K ! m/ log(D/m). In principle, such a sparse representation can be obtained by solving the optimization problem: ...

Estimating Covariate-Adjusted Log Hazard Ratios for Multiple Time
... applicable as estimators of hazard ratios when the survival times follow a piecewise exponential distribution for the intervals from the partition of time. In this article, these methods are improved upon via a nonparametric randomization based method for estimating covariateadjusted hazard ratios f ...

Experience Mining Google’s Production Console Logs
... Two limitations prevent us from quantitatively evaluating detection results. First, console logs in GX are not regularly used by system operators, and thus there are no manual labels explaining the logs. With an unclear “ground truth”, it is not possible to evaluate metrics such as true/false positi ...
