Initial High/Low Constraints for Factors

Click the Initial factor constraints (highs & lows) button on the Design Points (Vertices & Centroids) for Constrained Surfaces and Mixtures - Quick tab to display the Initial High/Low Constraints for Factors spreadsheet containing the initial factor constraints, that is, their minimum and maximum values. If the Type of design is set to Mixture design on the Quick tab, the spreadsheet will also show the mixture Total. Enter here the factor minima and maxima, and, for mixture designs, the mixture total. When processing the constraints, the computations performed by Statistica are performed in the highest possible floating-point precision. However, if the minima and maxima for different factors are of completely different magnitudes, it is recommended that you rescale the factors to make them compatible in size. Extreme differences in the orders of magnitude for different factors may cause round-off problems when a large number of constraints are processed. See also, General User Entry Spreadsheet.
