The aim of our study
is to reveal different timetrend patterns in the ratio of advertising
expenditure over gross domestic product for 28 European countries in the
period 19942004.
To fulfil the
objective we used two multidimensional statistical approaches: cluster
analysis and multidimensional scaling of timevarying data, followed by
a linear regression analysis of the timeseries within the clusters. The
proximity matrix was calculated using the dissimilarity between two time
series, which takes into account the order of time points, the
information on the fixed time points, and the weights which are
arbitrary. We identified four clusters of countries with similar trend
patterns in 19942004: awakening countries, stable countries,
catchingup countries and the leading cluster.
