Estimation and Prediction of Individual Ability in Longitudinal Studies
Door: Kamphuis, F. | 01-02-1992 First, the optimal solution to the estimation or prediction problem of individual ability ('states') is discussed in the frame work of the State Space Model (SSM).Next, the consequences of replacing the linear measurement model in the SSM by a nonlinear Item Response Model (IRT) are investigated.Finally, the possibility of using estimates of latent ability in IRT as pseudo observations in the SSM are explored.
