Silent Abandonment in Text-Based Contact Centers: Identifying, Quantifying, and Mitigating its Operational Impacts
Antonio Castellanos, Galit B. Yom-Tov, Yair Goldberg +1
In the quest to improve services, companies offer customers the option to interact with agents via texting. Such contact centers face unique challenges compared to traditional call…
Silent Abandonment in Contact Centers: Estimating Customer Patience from Uncertain Data
Antonio Castellanos, Galit B. Yom-Tov, Yair Goldberg
In the quest to improve services, companies offer customers the opportunity to interact with agents through contact centers, where the communication is mainly text-based. This has…
A zero-estimator approach for estimating the signal level in a high-dimensional model-free setting
Ilan Livne, David Azriel, Yair Goldberg
We study a high-dimensional regression setting under the assumption of known covariate distribution. We aim at estimating the amount of explained variation in the response by the b…
Improving Efficiency of Tests for Composite Null Hypotheses
Yotam Leibovici, Yair Goldberg
The goal of mediation analysis is to study the effect of exposure on an outcome interceded by a mediator. Two simple hypotheses are tested: the effect of the exposure on the mediat…
Improved Estimators for Semi-supervised High-dimensional Regression Model
Ilan Livne, David Azriel, Yair Goldberg
We study a linear high-dimensional regression model in a semi-supervised setting, where for many observations only the vector of covariates is given with no response . We do…
Semiparametric Analysis of the Proportional Likelihood Ratio Model and Omnibus Estimation Procedure
Yair Goldberg, Malka Gorfine
We provide a semi-parametric analysis for the proportional likelihood ratio model, proposed by Luo & Tsai (2012). We study the tangent spaces for both the parameter of interest and…
