We propose a novel conditional quantile prediction method based on complete subset averaging (CSA) for regressions. All models under consideration are potentially misspecified, and the dimension of regressors goes to infinity as sample size increases. Since we average over subsets, number is much larger than usual model which adopts sophisticated weighting schemes. use an equal weight but selec...

This paper elaborates on a sieving technique that has first been applied in 2018 for improving bounds deterministic integer factorization. We will generalize the sieve order to obtain polynomial-time reduction from factorization specific instance of multiple choice subset-sum problem. As an application, we improve upon special purpose algorithms integers composed divisors with small difference....
