核密度估计，在其最简单的可以被视为直方图的平滑形式，近年来在统计文献中得到了广泛的研究，但在考古学中几乎没有使用。他们提供了一个有效的方法，数据呈现单变量，特别是双变量数据，这是说明了一系列的例子。该方法可以作为一种非正式的空间聚类分析方法，一个例子表明，它是竞争力与其他方法在这一领域。考古学家不使用核密度估计的一个原因可能是缺乏可访问的软件。这里描述的分析是在MATLAB软件包中使用第二作者开发的例程进行的，可应要求提供。(C)出版社：Academic Press Limited。
Kernel density estimates, which at their simplest can be Viewed as a smoothed form of histogram, have been widely studied in the statistical literature in recent years but used hardly at all within archaeology. They provide an effective method of data presentation for univariate and particularly bivariate data and this is illustrated with a range of examples. The methodology can be used as an informal approach to spatial cluster analysis, and one example suggests that it is competetitive with other approaches in this area. A reason for the lack of use of kernel density estimates by archaeologists may be the lack of accessible software. The analyses described here were undertaken in the MATLAB package using routines developed by the second author, and are available on request. (C) 1997 Academic Press Limited.
