Department of Mathematical Statistics
About the Department
The Section of Mathematical Statistics was established on
April 1, 2004, as a unification of Section of
Statistics and Its Applications and Section of Applied Probability.
For brief history of the two last mentioned Sections see below.
The following researchers have been members of the Section of
Przemysław Biecek, Katarzyna Danielak,
Tadeusz Inglot, Teresa Ledwina, Ryszarda Rempała,
Tomasz Rychlik, Grzegorz Wyłupek and Ryszard Zieliński.
The main scientific interests have been focused on the

The Section of Mathematical Statistics and Its Applications stemmed from the Department of Applied Mathematics
of the State Institute of Mathematics, which was established in November 20, 1948.
In 1949 the Department consisted of six sections. Two of them: the General Section of Applications,
headed by Hugo Steinhaus, and the Section of Technical Applications, directed by Jan Mikusiński,
were located in Wrocław. These two sections formed later on the Section of Applications to Biology,
Economics and Technology, directed by Hugo Steinhaus until his retirement in 1960. Julian Perkal (1960-1965)
and Stefan Zubrzycki (1965-1968) were later directors. The Section has played a very important role in
the Wrocław scientific community, in particular through many collaborations with various professionals
and educational work in applied probability and statistics. The journal Zastosowania Matematyki
(the subtitle Applicationes Mathematicae added in 1965), founded by Hugo Steinhaus in 1953,
with help of Jan Oderfeld, was a significant platform for the activity of the group.
This activity was further supported by Julian Perkal, who founded the Listy Biometryczne journal in 1964.
The journal is currently published as Biometrical Letters.
From 1968 to 1991 the Section was headed by Witold Klonecki and was renamed to the Section of
Mathematical Statistics and Its Applications in 1973. At that time, the main activity was focused on
PhD studies in modern statistical methodology, initially with the kind aid of colleagues from Wrocław
University. Members of the group participated very actively in the organization of a series of conferences,
beginning with one in Wisła in 1973. Many of these conferences were international. Symposium to honour
Jerzy Neyman (1974), the European Meeting of Statisticians (1981) and Banach Center Semester on
Nonparametric and Robust Methods (1984) are prominent examples. Witold Klonecki was also one of the
founders of the Probability and Mathematical Statistics journal (1980).
Since 1991 until 2004 the Section was headed by Tadeusz Bednarski.
Apart from research in mathematical statistics, much attention was focused on direct applied work.

The Section of Applied Probability originated in a long process rooted in
the Department of Applied Mathematics of the State Mathematical Institute,
founded in 1948. Two Warsaw's sections of this department were forerunners of it. Namely,
the Section of Statistical Quality Control and the Actuarial Section.
In accordance with the evolving
interests of the members, the Section of Statistical Quality Control was renamed
to the Industrial Applications
Section in 1962. In the period from 1952 to 1970 these sections were directed
by Jan Oderfeld, with short break in 1959 when Czesław Rajski was in charge of it.
At that time, the research was mainly focused on statistical quality control, operations
research and reliability theory. The Actuarial Section evolved into the Section of
In 1951, Oskar Lange was put in charge of the section and he did it until 1958.
In 1958-1960 Marek Fisz was the leader of
it while later on the section was headed by Wiesław Sadowski.
Interests of the group were focused on statistics, decision making and
These two evolving groups were the predecessors the Applied Probability Section,
formally founded in 1972.
The section was
headed by Robert
Bartoszyński, Ryszard Zieliński and Tomasz Rychlik in the
periods 1972-1985, 1985-2002 and 2002-2004, respectively.
In the early seventies, the scientific interests of the group
switched to probabilistic modelling (mostly, but not only, of biological
phenomena), controlled Markov chains, stochastic approximation and random search.
In recent years, various issues of mathematical statistics, including robust statistics,
fixed precision estimation and moment bounds have become major focuses of
the section's research.
The section was active in the organization of courses in applied mathematics,
a wide spectrum of applied probability. Also, starting from 1971, Eugeniusz
annually organized the very popular
National Conferences on Applications of Mathematics. Members of the group
organized many international conferences in statistics, including Banach Center
