RegisterPeriod DFs [Regulatives / Guidelines]
Dear d_labes,
Important edit:
I apologise - overlooked that we are only dealing with the ref.
I will let my initial response remain below.
I am not sure this is the explanation, here's my logic:
If we for any observation for any subject within the i'th sequence have info abut which three periods the obserbation does not come from thenwe can infer which period it comes from. Thus df(per)=4-1=3.
Same for sequence, df(seq)=2-1.
For the subject; if we know which of the subjects it isn't then we can infer which subject (in seqs) it comes from (that's minus 1) and we can even infer which if it is the subject from seq 1 or seq 2 (minus 1 again). df(subj)=77-2=75.
75+3+1=79 (according to Excel, this is not on an early-age pentium machine
).
Will do, sir!
Please allow me a little time for that.
❝ Seems there is some inter-dependence between periods and sequences.
❝ Subjects with sequence TRTR have only periods 2 and 4, those with sequence RTRT have periods 1 and 3 (Note: we are dealing only with the data of the Reference).
❝ Maybe this is the source of this odd degree of freedom?
