A new algorithm for clustering life course trajectories is presented and tested with large register data. Life courses are represented as sequences on a monthly timescale for the working-life with an age span from 16-65. A meaningful clustering result for this kind of data provides interesting...

A number of contributions have found evidence for motherhood being a critical life event for women's employment careers. This study presents a detailed model for the du- ration of maternity leave in which young mothers can make a transition into a number of states related to employment and...

We consider the semiparametric generalised linear regression model which has mainstream empirical models such as the (partially) linear mean regression, logistic and multinomial regression as special cases. As an extension to related literature we allow a misclassified covariate to be interacted...
