举例----------Examples----------
groups.vector <-c("CT", "T1vsCT", "T2vsCT", "CT", "T1vsCT","T2vsCT", "CT", "T1vsCT", "T2vsCT")
coefficients <- c(0.1, 1.2, -0.8, 1.7, 3.3, 0.4, 0.0, 2.1, -0.9)
## calculate true regression coefficients for variable "T1"[#计算真正的回归系数为变量的“T1”]
reg.coeffs(coefficients, groups.vector = groups.vector, group = "T1")
