I am using UNSCRAMBLER X for soil spectroscopy. I was predicting some values with PLSR, but when I looked at the predicted vs. reference statistics, it showed me “NA” for the R-squared value. I was trying to find out why it doesn’t show zero or the actual value, but didn’t fi…

When we built a PLSR model and use this model to make predictions, on the unscrambler we obtained RMSEP value which is basically Predicted Value-Reference Value. Can you please guide us as to how we should calculate the standard deviation or error limits for the RMSEP values?…

The R-square statistic in Predicted vs. Reference is the value for the Explained Variance for the selected number of components (the same values you see in the Explained Variance plot in the Regression Overview window when building a PLS model). When…

The RMSE is a standard deviation (see formula in the attachment). You can report the predicted value with a confidence interval of 2 X RMSE (95% confidence interval). For example, for a prediction of 34.7% with an RMSE of 0.45, you would report it…

We understand the usefulness of scripting to streamline data analysis. We have taken it into consideration for future development of The Unscrambler, however this is still at an early stage. We will keep you updated on the progress.…

In The Unscrambler X, you can save plots in the emf (extended metafile format) which can then be edited in another program. In any plot, right mouse click, and select Save Plot.. and choose the .emf format.…
