Dear R-users, I need to standardize residuals using standard deviation. Is the 'stdres' the proper function? Beside other methods (for standardization and normalization), are there some approaches how to standardize using standard deviation? Here is the sample of my residuals: Zres040 Zres0820 Sres040 Sres0820 PCres040 -2.101740 -2.0682900 1.6328500 0.5046730 -0.005208170 1.203350 1.2594100 -1.6836200 -1.1871700 0.001087080 -0.724331 -0.8699000 -1.2246600 -0.2533400 0.002608070 -0.333226 -0.2219900 -1.5083400 -1.6578600 0.001130550 -1.850980 -1.8498800 6.7426900 7.6073600 -0.006078260 2.676660 2.5251400 3.4960500 1.9224600 0.005720740 -0.628793 -0.7680440 -0.7999610 0.7899290 0.007231940 Thanks in advance Rado -- Radoslav Bonk European Commission - DG Joint Research Centre (JRC) Institute of Environment and Sustainability (IES) LM Unit - Natural Hazards Via E.
