By examining the regression coefficient and the degree of correlation of variables, it was determined that only the components of design and production capacity, quality management systems and financial capacity were strongly and directly related to brand credibility (confirmation of Hypotheses 1, 2, 4, 9).Finally, the coefficient of model determination in this test was estimated to be 0.42%.
