Statistics for NIR Network Monitoring (SST, SSW and SSB)

I want to share this videos  from the Khan Acedemy, because the SST (Total Sum of Squares), SSW (Sum of Squares Within) and SSB (Sum of Square Between) are part of other which will help to develop other formulas trying to understand how a NIR Network performs (evaluating the predicted results from diferent  standardized NIR instruments in the Network).

I will continue with this in future posts
