This paper studies the test of joint significance for the ordered choice model with multiple explanatory variables following integrated processes. The results show that for the widely used logit and probit models, when true parameter vector of explanatory variables is zero, the classical Wald...

Constructing heterojunction has been considered as an efficient strategy to promote the separation and transfer of photogenerated carriers and improve redox ability of single photocatalyst. Herein, S-scheme BiOBr/Bi2S3 heterojunction with surface oxygen vacancies (OVs) was structured in situ by...
