求翻译:In the model specification, we consider structural zeros by introducing a structural weighting factor zijt,which equals 0 if either article i or j was not published during time period t and 1 otherwise (see Eq. (1)). This ensures thatestimated frequencies of structural zeros are actually zero and that Eq.是什么意思? 待解决

在模型的说明,我们认为结构前导零,实行一种结构性加权系数zijt,等于0如果任何一条或J是我不公布在时间t和1否则(见EQ。 (1))。 这确保thatestimated频率为零的结构实际上为零,EQ。

型号规格,在我们考虑引入加权因子 zijt,这等于 0,如果 I 或 j 仍未发表过程中任一条时间周期 t 和 1 否则 (见智商 (1)) 结构结构为零。这可以确保 thatestimated 频率的结构零是实际上是零和的智商
