What's New

2020-10-02 Programs added to TFQA:

  • calculate_K.  Calculates K for for use in Cowgill's formula that estimates the span of true interval  producing an observed set of measured dates with Gaussian errors. 
  • MatchInterval. Performs a MonteCarlo evaluation of the correspondence between temporal intervals with extreme climate events and the occurrence dates of major cultural changes
  • PhaseLen. Provides a Monte Carlo analysis to estimate the span of true span producing an observed set of measured dates with Gaussian errors such as radiocarbon and obsidian hydration dates.
  • Rarefy.  Performs pairwise rarefaction analysis of an for a set of sample counts in a CSV file.
  • RoomAccum. Estimates within-period rates of population growth (or decline) given structure counts dated to a sequence of chronological periods.

2007-07-21 EvalC performs a Monte Carlo evaluation of the significance of an observed value of Simpson's C relative to a given assumption about the population. It has been included in TFQA for several years but has not previously been noted or documented.

CntEdit and CntRefmt are companion program to cntcnv that permit reformatting and context-oriented editing of data files formatted for cntcnv. Like EvalC these programs have been included with TFQA (as CntCnvEd and CntCnv_Reformat) but are otherwise unnoted and undocumented.

2007-07-18 resampleBRED - A new program that provides Monte Carlo estimates of the sampling error of differences of the Brainerd-Robinson and Euclidean Distance coefficients calculated between a sample and a known population or between two samples drawn from the same population. This program does what BRSample does and adds calculations for Euclidean Distance calculation based on percents.

2007-01-07 Tools for Quantitative Archaeology (TFQA) gets a new permanent web site:  All of the documentation for the toolkit on the web at .  I hope that this may be more convenient for you and especially for users at site license locations.  With the web documentation everyone can take advantage of improvements to the documentation as I make them.  In particular, there are some fairly recent additions having to do with more efficiently running the tools under Windows For those of you using the tools in classes, please feel free to provide links to the site.  I will continue to make the last printed version available but from now on will not maintain the printed documentation.
