The estimation of variance by use of successive differences of higher order is discussed in this paper. Heretofore, attention has been focused, in published works, on estimates of variance obtained by ...

Researchers have successfully extended the quantum phase difference estimation algorithm, a general quantum algorithm for the direct calculations of energy gaps, to enable the direct calculation of ...

We compile a novel high-frequency, detailed geographic dataset on mass layoffs from U.S. state labor departments. Using recent advances in difference-in-difference estimation with staggered treatment, ...
