Although almost all employees have heard of or witnessed their colleagues being mistreated, we have an incomplete understanding of how employees perceive and respond to such events. Whereas past research has established that observer emotions can be congruent with victim emotions, we examine observer schadenfreude, an incongruent emotion that is also prevalent in organizations.

Certain estimation problems involving the covariance matrix in large dimensions are considered. Due to the breakdown of finite-dimensional asymptotic theory when the dimension is not negligible with respect to the sample size, it is necessary to resort to an alternative framework known as large-dimensional asymptotics. Recently, an estimator of the eigenvalues of the population…

These days, it is common practice to base inference about the coefficients in a hetoskedastic linear model on the ordinary least squares estimator in conjunction with using heteroskedasticity consistent standard errors. Even when the true form of heteroskedasticity is unknown, heteroskedasticity consistent standard errors can also used to base valid inference on a weighted least…
