On Consistency in Time Series Analysis
The Annals of Statistics, 1978 A number of statistics that arise in time series analysis can be represented as the sum of a partial realization of a possibly serially dependent and nonstationary discrete-parameter stochastic process. The almost sure and $L_p, p > 1$, convergence of such statistics is investigated, under various moment conditions. The results are applied to the least

The Econometric Analysis of Economic Time Series
International Statistical Review / Revue Internationale de Statistique, 1983 AbstractThis overview proposes a general framework linking economic analysis to a reduction‐based statistical methodology based on parameter change, expectations and contingent plans, conditioning and weak exogeneity. Both long‐run economic theory and dynamic adjustment are discussed and general‐to‐specific modelling is linked to the theory of ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Multiple Time Series Analysis [PDF]
, 2000 This chapter demonstrates how to use XploRe for specifying, estimating, and interpreting vector autoregressive (VAR) models. VAR modeling belongs to multiple time series analysis. It is one approach in econometrics to describe a system of more than one equation and was introduced by Sims (1980). The classical multi equation modeling (e.g. Dhrymes, 1978)

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA
FEBS Letters, EarlyView.The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

IMPLICATIONS OF DEFLATING COMMODITY PRICES FOR TIME-SERIES ANALYSIS [PDF]
The choice of deflators of commodity prices can change the time-series properties of the original series. This is a specific application of the general phenomenon that various kinds of data transformations can create spurious cycles that did not exist in

Time averaging, ageing and delay analysis of financial time series
New Journal of Physics, 2017 We introduce three strategies for the analysis of financial time series based on time averaged observables. These comprise the time averaged mean squared displacement (MSD) as well as the ageing and delay time methods for varying fractions of the ...

Circulant Matrices and Time-Series Analysis [PDF]
International Journal of Mathematical Education in Science and Technology, 2000 This paper sets forth some of the salient results in the algebra of circulant matrices which can be used in time-series analysis. It provides easy derivations of some results that are central to the analysis of statistical periodograms and empirical spectral density functions.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
