I would like to know:
How to detect if the data was performed log2() transformation?
For example,
data <- c(12, 23, 10, 6, 2, 8)
data
[1] 12 23 10 6 2 8
log2Data <- log2(data)
log2Data
[1] 3.584963 4.523562 3.321928 2.584963 1.000000 3.000000
Given the log2Data, how can I know if it is in the log2 space?
Thanks.
