- •
A synthetic set of ground motions is simulated using a recorded data set.
- •
The existing method is extended to 3-dimensional accelerograms.
- •
Several estimates of the joint pdf of the parameters are studied.
- •
A trade off between reproduction of the data set and statistical agreement between the recorded and the synthetic sets is necessary.
