does icc describe interclass correlation is the correlation between observation and a linear mixed model what is the relationship between an observation and a correlation between data and time why does icc relate longnitudial data what is the icc why is a correlation between variables linear mixed model? why is the icc in a linear mixed model how does interclass correlation work in a mixed model is correlation of the independent variable linear mixed why is the correlation matrix in a mixed model important? what is the icc of longitudinal data why does correlation between time periods need an icc what is intraclass correlation how is the icc related to correlation why does the interval of correlation in the longitudinal data what is the intraclass correlation in the icc why is icc an intraclass correlation how does icc work longitudinally what is the icc for longitudinal data how does icks work for longnitudial data
