F. Ter Hofstede et M. Wedel, Time-aggregation effects on the baseline of continuous-time and discrete-time hazard models, ECON LETT, 63(2), 1999, pp. 145-150
In this study we reinvestigate the effect of time-aggregation for discrete-
and continuous-time hazard models. We reanalyze the results of a previous
Monte Carlo study by ter Hofstede and Wedel (1998), in which the effects of
time-aggregation on the parameter estimates of hazard models were investig
ated. Whereas the previous study shows that the estimates of the baseline p
arameters of continuous- and discrete-time models suffer a lot from time-ag
gregation, we show that the effects on the baseline hazard itself are much
smaller, in particular for the continuous-time model. (C) 1999 Elsevier Sci
