TLDR
The level of overall density, its trend over cambial ages and the growth amplitude altered due to the sample pretreatment/density measuring exercise, which means that comparisons of heterogeneous datasets should be, in general, regarded cautiously.About:

Potential bias in 'updating' tree-ring chronologies using regional curve standardisation: Re-processing 1500 years of Torneträsk density and ring-width data
TL;DR: In this article, the analysis of existing and new maximum-latewood-density (MXD) and tree-ring width (TRW) data from the Tornetrask region of northern Sweden and the construction of 1500 year chronologies were described.
Journal ArticleDOI
Reassessing the evidence for tree-growth and inferred temperature change during the Common Era in Yamalia, northwest Siberia
Keith R. Briffa,Thomas M. Melvin,Timothy J. Osborn,R. M. Hantemirov,Alexander V. Kirdyanov,V. Mazepa,S. G. Shiyatov,Jan Esper +7 more
TL;DR: In this article, the authors reviewed the development of research into the history of tree growth and inferred summer temperature changes in Yamalia spanning the last 2000 years, incorporating different applications of Regional Curve Standardisation (RCS).

TL;DR: A demonstration of the need for mass/volume-based recalibration to accurately estimate average ring density and insights into the relevance of analytical measurement resolution in signals derived from tree-ring density data are provided.
Journal ArticleDOI
Testing long-term summer temperature reconstruction based on maximum density chronologies obtained by reanalysis of tree-ring data sets from northernmost Sweden and Finland
V. V. Matskovsky,Samuli Helama +1 more
TL;DR: In this paper, a correction implementation of signal-free standardization is proposed for detecting pure low-frequency signal in tree-ring chronologies, which is tailored for detection of pure lowfrequency signal.

3D tree-ring analysis using helical X-ray tomography
Jan Van den Bulcke,Erik L. G. Wernersson,Manuel Dierick,Denis Van Loo,Bert Masschaele,Loes Brabant,Matthieu Boone,Luc Van Hoorebeke,Kristof Haneca,Anders Brun,Cris L. Luengo Hendriks,Joris Van Acker +11 more
TL;DR: The current state-of-the-art of tree-ring analysis and densitometry is still mainly limited to two dimensions and mostly requires proper treatment of the surface of the samples as mentioned in this paper.

Bootstrap Methods for Standard Errors, Confidence Intervals, and Other Measures of Statistical Accuracy
Bradley Efron,Robert Tibshirani +1 more
TL;DR: The bootstrap is extended to other measures of statistical accuracy such as bias and prediction error, and to complicated data structures such as time series, censored data, and regression models.
Journal Article
Computer-Assisted Quality Control in Tree-Ring Dating and Measurement
TL;DR: In this article, a computer program for objectively checking tree-ring measurement series and aiding in the cross-dating process is presented, which can be used to determine the dating of tree -ring site collections from areas of somewhat difficult crossdating.
Book
Tree Rings and Climate
