had shown that consumer’s behavioural patterns and intentions are sources
of business profit level. In the advent wave of global businesses, the behavioural
buying patterns of consumers have to be studied and analysed. Hence, this research
illustrated the procedures in getting the best polynomial regression model of
the consumer buying patterns on the demand for detergent that had included interaction
variables. Methods: The hierarchically multiple polynomial regression
models involved were up to the third-order polynomial and all the possible models
were also considered. The possible models were reduced to several selected models
using progressive removal of multicollinearity variables and elimination of
insignificant variables. To enhance the understanding of the whole concept in
this study, multiple polynomial regressions with eight selection criteria (8SC)
had been explored and presented in the process of getting the best model from
a set of selected models. Results: A numerical illustration on the demand
of detergent had been included to get a clear picture of the process in getting
the best polynomial order model. There were two single independent variables:
the "price difference” between the price offered by the enterprise and
the average industry price of competitors’ similar detergents (in US$)
and advertising expenditure (in US$). Conclusion: In conclusion, the
best cubic model was obtained where the parameters involved in the model were
estimated using ordinary least square method.]]>Sandy, R.,1990Gujarati, D.N.,2006Pasha, G.R.,2002Smith, R.T. and R.B. Minton,2007Beach, E.F.,1950Wackerly, D.D., W. Mendenhall and R.L.
