本文对一年生树木年轮宽度和年轮指数序列进行了统计分析。在任何一年的增长的期望值被证明是成比例的标准偏差的增长，使变异系数是一个衡量的敏感性的增长的树。树木年轮数据被发现是非随机分布的时间。序列相关系数较大，说明这种非随机性不能完全归因于气候因素。相关图和功率谱分析应用到一个序列的树轮指数的一个pinyon松表明，数据产生的自回归过程。衡量增长的灵敏度或自满度的统计参数用于导出增长函数。
Abstract A statistical analysis is made of the sequences of annual tree ring widths and indices. The expected value of growth during any year is shown to be proportional to the standard deviation of the growth, so that the coefficient of variation is a measure of the sensitivity of the growth of a tree. Tree ring data were found to be non-randomly distributed in time. The large values of serial correlation indicated that the non-randomness cannot be attributed entirely to climatic factors. Correlogram and power spectrum analyses applied to a sequence of tree ring indices for a pinyon pine showed that the data were generated by an autoregressive process. The statistical parameter measuring the sensitivity or complacency of growth is used to derive a growth function.
