Application of the bootstrap-method in assessment of target strength regression parameters on the basis of in situ measurements
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 ... the adopted mapping rule of fishing data into acoustic data.
