Hi,
I am fitting a multievent model. Hereafter one of the matrix of constraint I am using:
* sa - - sb - - - - - - -
- * - - - - - - - - - -
- - * - - - - - - - - -
- - sa+ * - sb - - - - - -
- - - - * - - - - - - -
- - - - - * - - - - - -
- - - - - - * - - - - -
- - - - - - - * - - - -
- - - - - - sb+ - * sa - -
- - - - - - - - - * - -
- - - - - - - - - - * -
- - - - - - - sb+ - - sa+ *
- - - * - sb - - - - - -
- - - * - sb - - - - - -
- - - - - - - - * sa - -
- - - - - - - - * sa - -
- - - - - - - - - - sa+ *
- - - - - - - - - - sa+ *
- - - - - - - sb+ - - - *
- - - - - - - sb+ - - - *
All the states are mutually exclusive. I want all 'sa' parameters to be identical (and the same for sa+, sb and sb+ respectively).
so for example, for 'sa' I am using the gemaco sentence 'from(1 9 15 16).to(2 10)' or simply 'to(2 10)'.
Using either the first or the second sentence, I have indeed four parameters, one for each s, as I expected. But surprisingly, I get 3 different estimates per parameters, for example, for sa, I get one estimate
for transitions from(1).to(2), one for transition from(9).to(10) and one for transition from(15 16).to 10. I don't understand why.
Is this result mean that I can't constrain the parameters to be equal using this matrix?
thanks in advance
Alex
