我现在的课题是血浆中的各种因子对血小板计数的影响, 样本量大概有100例
各项指标已经确定,数据已得到,血小板分伤后不同时段进行计数,
目前有其他影响血小板的指标8项 应该应用什么统计学方法进行统计?
目的为确定因素与血小板计数的相关性分析,求各位老鸟指导。
小弟在此拜谢

能否详细一点,也许可以用回归分析。

you can try longitudinal data analysis via mixed model.
USING SAS Proc MIXED, time as a random effect, which takes the correlation between different time points into account within each subject.

the 8 variables that may affecting the blood platelet are time-fixed or time-independent?
da_da_mao
the 8 variables should be treated as fixed effect and time as random effect.
