Where ABRN = abnormal return, SCRN = supply chain relationship, INTL = integration level, and FISZ = firm size.
ABRN = [alpha] + .195(FISZ) -.344(SCRN) + .503(INTL)
In testing the null hypothesis that there is no relationship between abnormal return (ABRN) as measured by each of the independent variables at the .05 significance level, the null hypothesis can be rejected for firm size (FISZ), and integration level (INTL).
