Description Usage Arguments Details Value Author(s) Examples

This function calculates the score vector needed for the estimation of multistate models using the Fisher scoring algorithm.

1	scorevector(beta, X, risksetlist, event)

`beta`	vector of regression coefficients.
`X`	design matrix.
`risksetlist`	list of length `n` with vectors as list elements, with the i-th element being the riskset belonging to the i-th spell.
`event`	non-censoring event indicator.

This function implements the score vector (i.e., the first partial derivative of the log partial likelihood with respect to the components of the regression effect vector beta).
