Bootstrap and Jackknife Parameter Estimation of the Models Fitting to Lactation Milk Yield (2x305) on Calving Age

Abstract

Sahinler, S. and Karakok, S.G. 2008. Bootstrap and jackknife parameter estimation of the models fitting to lactation milk yield (2x305) on calving age. J. Appl. Anim. Res., 34: 39–44.

To predict lactation milk yield as dependent upon calving age 5 of the best-known mathematical models based on least squares, bootstrap and jackknife regression were fitted to data and several criteria based on the analysis were used to compare models. The second order, Ali and Schaffer and Wood models were determined better than other models, first one being the best in view ofR², AIC and BIC and the best fitting method was the bootstrap.
