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?…

I have been using Unscrambler X for eight year on a daily basis. Would it be possible to create a script to perform a similar analysis on different datasets placed in one directory ? This will allow me to keep on ising Unscrambler X ? Elsewhere, to cope with my needs, I will have to […]…

I am building Partial Least Square regression models (Tasks – Analyze – PLS) using the uncertainty test to find significant variables. After calculating the model it is possible to see the graphical version (graphical view) of the various results/ plots but also as a table (numerical view.) …

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…
