How to estimate the residual SD for each sample separately in mixed-effects model?
Dear R-helpers,
I am developing a Mixed-Effects model for a study of immunoassays using
'lme4' library. The study design is as follows: 10 samples were run
using 7 different immunoassays, 3 times each, in duplicates. Data
attached. I have developed the following model:
c.lme <- lmer(Result~SPL + (SPL|Assay/Run) -1, data=data)
This model has excellent predictions - the Rsquared of
