Sa. Murphy, A CENTRAL-LIMIT-THEOREM FOR LOCAL MARTINGALES WITH APPLICATIONS TO THE ANALYSIS OF LONGITUDINAL DATA, Scandinavian journal of statistics, 22(3), 1995, pp. 279-294
A functional central limit theorem for a local square integrable marti
ngale with persistent discontinuities is given. By persistent disconti
nuities, it is meant that the martingale has jumps which do not vanish
asymptotically, This central limit theorem is motivated by problems i
n the analysis of longitudinal and life history data.
