Multivariate regression analysis

A method for stepwise regression analysis comprising

• accessing a set of data specific to a business environment wherein the set of data comprises a set of values for a set of variables that describe the business environment;
• receiving a selection of a first variable from the set of variables;
• generating a correlation table, wherein the correlation table is generated by determining a correlation between the first variable and each remaining variable in the set of variables;
• and
• rank-ordering each of the remaining variables in the set of variables based on the correlation;
• and
• displaying the correlation table.

A method for stepwise regression analysis comprising

• receiving a request to create a demand chart showing an aggregate demand for a set of data specific to a business environment wherein the set of data comprises a set of values for a set of features that describe the business environment;
• creating a set of bins to separate the set of data in the demand chart;
• creating a demand frontier curve, comprising a curve showing the highest value in the set of values for each set of bins;
• creating an average demand curve, comprising a curve which shows an average for each of the set of bins and is determined by determining the average for the set of values for each of the set of bins;
• and
• determining an aggregate demand curve based on the demand frontier curve and the average demand curve.
