Patent ID: 7584164

Claim:
A computer implemented method for displaying values for a fuel price variable indicative of a prediction of a competitor's price change, the method comprising; displaying a first user interface element configured to present values of a first input variable affecting said fuel price variable; displaying a second user interlace element configured to present values of a second input variable affecting said fuel price variable; displaying a third user interlace element configured to present values of the fuel price variable indicative of a prediction of a competitor's price change, said fuel price variable varying in dependence upon said first and second input variables; receiving first user input of a value for said first variable via said first user interlace element; receiving second user input of a value for said second variable via said second user interface element; storing a set of values of said fuel price variable; determining a probability for each of said values of said fuel price variable indicative of a prediction of a competitor's price change based upon values of said first and second input variables; and updating said displayed third user interface element in response to said first user input and said second user input to represent said determined probabilities of said fuel price variable indicative of a prediction of a competitor's price change.
