FOSS CALIBRATOR: Tutorial 006



A calibration is robust if independently of the validation and training sets their predictions are robust as well, so we can try with different sets for training and validation selected randomly, time based, retaining parameter distribution,.....

Foss Calibrator can help quite a lot in this part as you can see in the video.

Water Absortion in Wheat Flour

Undertand you product and the parameters of that product it is very important for the development of the calibration. XY Plots and Residuals plot helps to understand them you use colors, symbols or other resources to create them.

In this case is a validation of water absortion in wheat flour, and all the samples are represented (low, medium and high strength (Flojas, Media Fuerza y Fuerza) , and  some use aditives and others not. 

Filters and other functions of ggplot or R, help to see the figures in more details and get interesting information to improve the calibration.

FOSS CALIBRATOR: Tutorial 005


Time to create the outlier model to predict the Mahalanobis distances in the principal component space.

FOSS CALIBRATOR: Tutorial 004


This is the video number 4 for the Foss Calibrator tutorials in spanish, where a model is developed using the MPLS algorithm. After the model calculation we can see several plots and statistics.
Foss calibrator is very fast for this types of models so we can do several almost at the same time and choose the best one.
Review the statistics and plots trying to finds patterns, outliers,...,etc

Creating a Single Sample Standardization



We create two single sample standardization files, one with the NIR5000 as Master and the DS2500F as Host , and other with the NIR5000 as Host and the DS2500F as Master. 

Depending of the scenario we can use one or the other.
