The XXVIII Conference on Multivariate Statistical Analysis was held from 16th to 18th November 2009 in Łódź. Organization of the conference was charged to the Chair of Statistical Methods, University of Łódź and Polish Statistical Association. The conference presented the latest theoretical achievements in the field of the multivariate statistical analysis and its applications. This is a continuation of the issues undertaken on the conferences organized in the past years. The scientific programme of MSA 2009 covered a range of statistical problems, such as: multivariate distributions, statistical tests, nonparametric inference, discrimination analysis, Monte Carlo analysis, Bayesian inference, application of statistical methods finance, insurance, capital markets and risk management.

This year the open meeting of Committee of Statistics and Econometrics PAN was held as part of the Conference. On the meeting, Prof. Agnieszka Rossa delivered a lecture “Stochastic models of population dynamics”.

Altogether, there were 70 participants from various academic and research centres in Poland. Concerning the papers, 43 papers were presented in 13 sessions.

The conferences were opened by the Chairman of the Organizing Committee:

Prof. Czesław Domański. The opening speech was also given by the Pro-vice

Chancellor of the University of Łódź Prof. Antoni Różalski and the Dean of the Faculty of Economics and Sociology of the University of Łódź Prof. Jan Gajda.

The first plenary session (chair: Prof. Janusz Wywiał) was devoted to famous Polish statisticians: Stanisław Marcin Ulam (1909–1984) and Ludwik Krzywicki

(1859–1941).

Prof. Mirosław Krzyśko (Adam Mickiewicz University in Poznań) reported

a paper titled “Stanislaw Marcin Ulam”. Stanislaw Marcin Ulam (born April 13, 1909, Lwów, died May 13, 1984, Santa Fe, New Mexico, U.S.) was a Polish and American Mathematician (in 1943 he became a U.S. citizen) who helped to develop the Teller-Ulam design which powers the hydrogen bomb, as well as a number of other important mathematical tools (branching processes, Monte Carlo method).

Prof. Czesław Domański (University of Łódź) delivered a lecture about “Ludwik Krzywicki”. Ludwik Krzywicki (born August 21, 1859, Płock, died,

June 10, 1941, Warsaw) was a Polish anthropologist, economist and sociologist. One of the early champions of sociology in Poland, he approached historical materialism from sociological viewpoint. Krzywicki studied mathematics at the University of Warsaw in Poland. Later he began studying anthropology, archaeology and ethnology among others in Paris. From 1919 to 1936 he was a professor at the University of Warsaw.
