I have checked and found that the results are identical, after fixing the issue spotted in #17

in the design there are extra control to 1. ensure unbiasness in prediction (causing 1e-15 difference) 2. use decompose method to obtain the variance instead of calculate the variance of residuals (causing 1e-7 difference)

[clarkliming]

the code in all_draft_functions.R and the documentation can be a good source of qc/vignettes, however probably we can have better strucutres, e.g. add another folder instead of duplicating the current design.rmd files
