Multiple conditional randomization tests for lagged and spillover treatment effects
Yao Zhang, Qingyuan Zhao
We consider the problem of constructing multiple independent conditional randomization tests using a single dataset. Because the tests are independent, the randomization p-values c…
On testing mean proportionality of multivariate normal variables
Etaash Katiyar, Qingyuan Zhao
This short note considers the problem of testing the null hypothesis that the mean values of two multivariate normal variables are proportional. We show that the usual likelihood r…
Two-sample instrumental variable analyses using heterogeneous samples
Qingyuan Zhao, Jingshu Wang, Jack Bowden +1
Instrumental variable analysis is a widely used method to estimate causal effects in the presence of unmeasured confounding. When the instruments, exposure and outcome are not meas…
Permutation p-value approximation via generalized Stolarsky invariance
Hera Yu He, Kinjal Basu, Qingyuan Zhao +1
It is common for genomic data analysis to use -values from a large number of permutation tests. The multiplicity of tests may require very tiny -values in order to reject any…
