Iron nitride is a promising anode material with ultrahigh theoretical capacity and excellent electrical conductivity. Nevertheless, due to the poor stability of metal nitrides on account of their amorphous and powdering in the long-term charging and discharging process, their electrochemical...

When missing data are produced by a non-ignorable nonresponse mechanism, analysis of the observed data should include a model for the probabilities of responding. In this paper we propose such models for nonresponse in survey questions which are treated as multiple-item measures of latent...
