in MSA edition 3,there are some equations for linearity analysis. like "s2=(∑yi2 – b ∑yi – a∑xiyi)/(gm-2)" in page 93, i am confused about how to use these eqations.for example, in the manual,it points out that "xi" is the refence value, does it mean "xi" is "2,4,6,8,10" as given in the example in page 94? as to "yi", does "yi" is the "bias average", like "0.491667,0.125, 0.025,-0.29167, -0.61667"? if "xi" and "yi" present the numbles as i thought,then we can't calculate out the value "ta","tb" as given in page 96. the equations is really confusing, i wonder if anyone can help me to make them clearer.
thank you very much!
