Bootstrap sampling is a nonparametric method for estimating the standard er
ror of a statistic. This paper describes the application of bootstrap sampl
ing to estimate the error in local linear approximations of the dynamics on
chaotic attractors reconstructed from time series measurements. We present
an algorithm for identifying influential points, i.e., observations with a
n especially large effect on a least-squares fit, and an algorithm to estim
ate the standard error of regression coefficients obtained from total least
squares. We also consider the application of bootstrap methods to assess t
he uncertainty in Lyapunov exponent computations from chaotic time series.
