Stability of household income in European countries in the 1990s
Nick Longford, SNTL, Leicester, UK
(with M.G. Pittau, University of Rome 'la Sapienza', Rome, Italy)
The talk explores the patterns of change in the annual household income
in the countries of the European Community during the years 1994-1999.
The income is modelled by mixtures of log-normal distributions, and the
mixture components are interpreted as representing one subpopulation
with steady increments and others
with various levels of volatility. The method is extended to models for
a combination of log-normal and categorical variables. An index of
income stability is defined for the countries. Graphical summaries of
the results are emphasized. The advantages of mixtures and kernel
smoothing are critically evaluated.
Current and planned research in other applications of mixture models
will be outlined.
