The abovementioned four regression models were estimated,
initially through ordinary least squares (OLS) and then through
ordered probit (ordinal regression), using the PASW Statistics
18.00 SPSS statistical software package. The results with respect to
the statistical significances of the independent variables were
identical, which indicates their robustness. In Table 1 we can see
the estimated four models using OLS, having as dependent
variables the impacts of ICT on the four business performance
perspectives/dimensions proposed by the balanced scorecard
approach: financial performance (ICT_FINP), value offered to
customers (ICT_CUSV), performance of business processes (ICT_BPRO)
and innovation (ICT_INNO); for each model we can see the
standardized coefficients of the independent variables, which
allow a comparison of the effects of them on the dependent
variable.
