Helper function to calculate CV(T) and CV(R) from a pooled CV(T/R) assuming a ratio of the intra-subject variances.
CVp2CV(CV, ratio = 1.5)
‘pooled’ CV of T and R (as ratio, not percent).
Ratio of the intra-subject variances
In case of knowing only the CV(T/R) f.i. from an ordinary cross-over you can
calculate the components CV(T) and CV(R) assuming a ratio of the
The formula the function is based on:
log(1.0 + CV^2) = (sWT^2 + sWR^2)/2
sWT^2 = ratio * sWR^2 and solve for
Returns a numeric vector of the CV values for Test and Reference if only
one ratio is given.
Returns a matrix with named columns
CVwR if ratio is given as vector.

CVp2CV(0.4, ratio=2) # gives #  0.4677952 0.3225018
 0.4677952 0.3225018
