rds22
Reference dataset 22
Simulated with CVwT = CVwR = 45%, CVbT = CVbR = 100% GMR 0.90. 42 subjects.
Balanced (21 subjects in each of the sequences) and complete (no missing data). No outliers.
A data frame with 126 observations on the following 5 variables:
subject | a factor with 42 levels: 1, 2, ..., 42 |
period | a factor with 3 levels: 1, 2, 3 |
sequence | a factor with 2 levels: TRR, RTR |
treatment | a factor with 2 levels: T, R |
PK | a numeric vector of pharmacokinetic responses acceptable for reference-scaling |
logPK | a numeric vector of the natural logarithms of PK
|
Dataset | N | CwR (%) | Evaluation |
rds22 | 42 | >30 | method.A() , method.B()
|
In software sequences and treatments are ranked in lexical order. Hence, executing str()
or summary()
will show sequence
as "RTR", "TRR"
and treatment
as "R", "T"
. In BE – by convention – sequences are ordered with T
first. The package follows this convention.
This partial replicate design is also known as the ‘extra-reference design’. Since the Test is not administered in all periods, lacking period effects must be assumed. In the presence of true period effects the treatment comparison will be biased. Hence, this design is not recommended.
