"Correlation is not the most important statistic in regression analysis. The standard error of prediction (SEP) which is the error in predicting the independent validation samples is the first test of any NIR method. You can compare this to the SER for your reference analysis.
Hope this helps,
Best wishes,
Tony"
"The correlation coefficient is influenced by the range. The most important information is given to us by the SEP which answers the question "How variable are the answers from this model"? If the SEP is less than that required for the analysis then you have a method. R and r^2 are important but not the most important or useful statistics.
Best wishes,
Tony"
