  Tethered particle motion experiments are versatile single-molecule techniques
enabling one to address in vitro the molecular properties of DNA and its
interactions with various partners involved in genetic regulations. These
techniques provide raw data such as the tracked particle amplitude of movement,
from which relevant information about DNA conformations or states must be
recovered. Solving this inverse problem appeals to specific theoretical tools
that have been designed in the two last decades, together with the data
pre-processing procedures that ought to be implemented to avoid biases inherent
to these experimental techniques. These statistical tools and models are
reviewed in this paper.
