Application of the bootstrap-method in assessment of target strength regression parameters on the basis of in situ measurements
(PDFs) of fish length and target strength at 38 kHz and truncated PDFs are presented. We reveal that it ... Abstract: Target strength (TS) as a function of fish length (L) must be known to estimate fish ... characterizing the uncertainty of its parameters. We show that the bootstrap–method is a highly efficient method ... of estimating the parameters of TS-length function and emphasize that calculation results depend on ...
