Hi R-helpers,
I am having a problem understanding how to construct the qmatrix, i have
read the help menu for msm but I am still a bit lost. Below is an example of
one of my transition matrices:
statetable.msm(BEH, ID, data = A1)
to
from 1 2 3 4 5 23 200 201 203 999
1 86 11 2 20 1 9 3 11 1 22
2 18 4 4 4 0 1 1 1 0 1
3 5 2 0 5 0 0 2 0 0 3
4 17 5 5 13 0 4 3 3 0 7
5 1 0 1 1 0 0 0 0 0 0
23 7 3 0 4 0 3 1 3 0 3
200 5 0 2 3 1 2 1 3 0 3
201 5 5 3 2 1 0 2 6 1 5
203 3 0 0 0 0 0 0 0 0 0
999 18 4 0 5 0 5 7 3 1 0
Instantaneous transition IS allowed from state r to state s. But what i
don't understand is what is the logical way to create the initial transition
matrix - i've tried to just give even numbers to all transition
possibilities e.g. every transition given 0.1 or 1, but i get the following
error message:
Error in msm.check.state(nrow(qmatrix), state, cens$censor) :
State vector contains elements not in 1, 2, ... , 10
Does anyone have any suggestions, i can only assume that this is a simple
problem that i have overlooked because nobody else seems to have asked it!
Any suggestions on how to construct a qmatrix would be much appreciated,
Berst wishes,
Ross
