Resummation Methods for Analyzing Time Series
An approach is suggested for analyzing time series by means of resummation
techniques of theoretical physics. A particular form of such an analysis, based
on the algebraic self-similar renormalization, is developed and illustrated by
several examples from the stock market time series.Comment: Corrections are made to match the published versio
Renormalization Group Analysis of October Market Crashes
The self-similar analysis of time series, suggested earlier by the authors,
is applied to the description of market crises. The main attention is payed to
the October 1929, 1987 and 1997 stock market crises, which can be successfully
treated by the suggested approach. The analogy between market crashes and
critical phenomena is emphasized.Comment: Corrections are made to match the published versio
