In nicksun1/Biomarker-Analysis: MMRM Analysis of New Biomarker

# Biomarker Regression Analysis
#
# Summary and Analysis of UACR including percent change from baseline via log-transformed analysis MMRM from baseline through 52 weeks
# Least square mean percent change and standard error
#
# Fit to model log(y) = log(y_b) + trt
# After model is finished transform back by LSM=exp(LSM) and SE=exp(LSM)*SE
#
# Also find geometric mean and SE
# (Find n, lsm, geometric mean, se for baseline, post-baseline (week 52), change from baseline and percent change from baseline)
#
# Placebo controlled (Study CF, Study G, Study A, Study I), Insulin Glargine (Study B, Study D, Study X)
