The following performance results are for general comparison and expectation. Your own mileage may vary.
This page presents performance results from the main regression methods in PLS_Toolbox to allow comparison of their time and memory requirements when analyzing datasets of various sizes. These results were obtained using a Mac OSX (El Capitan) computer with a 2.8 GHz Intel CPU and 16 GB RAM. Matlab version R2015a and PLS_Toolbox version 8.1 were used.


All results were obtained by building models from the command line using synthetic random datasets. Autoscale preprocessing was used with the default option values for all methods.  Cross-validation was not performed.

PLS_Toolbox Performance

This page presents performance results from the main regression methods in PLS_Toolbox to allow comparison of their time and memory requirements when analyzing datasets of various sizes. These results were obtained using a Mac OSX (El Capitan) computer with a 2.8 GHz Intel CPU and 16 GB RAM. Matlab version R2015a and PLS_Toolbox version 8.1 were used.

All results were obtained by building models from the command line using synthetic random datasets. Autoscale preprocessing was used with the default option values for all methods. Cross-validation was not performed.
