Abstract

In this article, we propose a methodology for the validation of sequence analysis typologies based on bootstraps. The method works by comparing the quality of the obtained clustering with the quality obtained by clustering similar but unstructured data. Several models are proposed in order to test the different structuring aspects of the sequences that are important in life course research, namely sequencing, timing and duration. The framework is extended to multichannel sequence analysis by looking at the structure stemming from the association between the channels.

Abstract

The Great Recession had a profound impact on the labour market. Unemployment increased substantially and rapidly in almost all developed countries in the aftermath. While the unemployment rate began to decrease shortly after the crisis, this did not necessarily translate into a return to pre-recession levels. In fact, it took ten years for employment levels to recover to pre-2008 levels.
