❝ It seems not so difficult to implement TTT method using R. Meanwhile, it is easy to validate visually. Thanks.


without the for loop:
b<-c(0,0.25,0.5,0.75,1,1.5,2,3,4,8,12,24)
c<-c(0,30.1,211,1221,1485,1837,1615,1621,1411,763,424,109)
dat <- data.frame(time=b,conc=c)
x<-which.max(dat$conc)
summary(lm(log(conc)~time,dat[dat$time>=(dat$time[x]*2),]))
