Özet

The aim of the study is to find out, the utility function of factor analysis scores in multiple linear regression model that were used to estimate body weight with respect to some body measurements (total length, standard length, fork length, head length, body depth, body circuit, body height) measured from Lizardfish in Iskenderun Bay. The results of the factor analysis showed that 3 factor with eigenvalues greater than I can be selected as explanatory variables and used to estimate body weight of Lizardfish in multiple linear regression model. The factors accounted for 98.4% of total variation in the body weight.
