«Select a template»There are no templates in the project. Clicking the «+» creates one.
The X box in a column is disabledA constant column, or one with a repetition factor greater than 1. A column with no variation has no measurable effect.
The Gaussian process does not appear in the typesAn "X" is qualitative, or the grid has more than 50 rows.
The K-OPLS regression does not appearThe table is too large (more than 2,000 values in the selected columns).
The X and Y have been removed from the modelThe model grid has been changed: the selection has been reset.
Excellent R², but test lines were poorly predictedOverfitting. Simplify the model or revert to the default settings.
«No terms in the model»Check the terms in the selector on the left.
High VIFs across multiple termsRedundant factors: The coefficients are not separable. Remove a term, or expand the experimental design.
The optimum lies on a boundary of the domainThe true optimum is probably beyond that. Expand the range through further testing; do not extrapolate.
«The model requires at least 4 measured trials.»Enter the results of the initial tests.
«First, enter the pending test results»A lot that has been offered has not yet been measured.
«At least two measured trials are required» (convergence)This is normal at the beginning of the study.
«A response surface requires at least two factors.»The map requires two factors; the 5D graph requires four.
Coverage below 95 % at diagnosisThe model underestimates its uncertainty: increase the expected noise or add more tests.
High Noise WarningCheck the repeatability of the measurement before continuing.
Sum of proportions not equal to 1 (mixture)Edit the essay, or use the auto-correct feature.
Infeasible mixing terminalsThe minimums add up to more than 1, or the maximums add up to less than 1. Review the bounds.
