Forecast Dates Specify whether the forecast spread will be based on early, late, or default forecast dates. The early and late dates are used for best- and worst-case forecast scenarios.
Performance factor level This field controls the level at which Cobra calculates the CPI and SPI.
  • Levels 1-20

    The levels represent the hierarchical structure of a code file. Selecting a level instructs Cobra to perform forecast calculation at that level for the selected code file.

Code File This field displays if you select any of the levels from 1 to 20 in the Performance factor level field. Use this field to select a code file to calculate forecasts against.
Define Relative Weighing Enter the values for the a and b parameters in the PF=1/(a*CPI+b*SPI) method. By specifying the a and b factors, you can define a performance factor that reflects the cumulative CPI/SPI, where the relative weights of CPI and SPI are user defined.

The combined relative weights of both fields must be equal to 1.
