[問題] 中介變項是count data

[evilove (願意感動就是一種享受)]

各位好，
我現在要處理的資料中介變項是count data
依變項也是count data
我找過工具變項相關的論文，像是：

Terza, J. V. (2002). ‘Alcohol Abuse and Employment: A Second Look. Journal
of Applied Econometrics 17: 393–404.
Terza, J. V., Basu, A., & Rathouz, P. J. (2008). Two-stage residual inclusion
estimation: Addressing endogeneity in health econometric modeling. Journal of
Health Economics, 27(3), 531-543.
Terza, J. V., Bradford, W D., and Dismuke, C. E. (2008). The Use of Linear
Instrumental Variables Methods in Health Services Research and Health
Economics: A Cautionary Note. Health Research and Educational Trust, 43(3),
1102–1120.
Staub, Kevin (2009) “Simple tests for exogeneity of a binary explanatory
variable in count data regression models.” No 904, Working Papers from
University of Zurich, Socioeconomic Institute.

或是上Mplus的論壇去看，都沒看到有人解決關於中介變項是count data的議題，

不知道有沒有大大有相關的論文或參考文獻可以分享
或是知道怎麼樣處理這類的模型

感恩～
