Document Summary

Line of best fit and see (prediction error) residual = reference predicted line of best fit = regression line for relationship between measured predicted scores and. See = how far away the predicted are from the line of best fit. Good, valid test if : high r value, as close to 1 as possible, as low a possible see. Take a criterion, eg. ffm (gold standard measure of ffm), vs. resistance index of bioelectrical impedance to find out how good it is at predicting someone"s ffm value. Residual value = value of reference method predicted; actual difference between scores obtained from the two methods. Reliable ability to reproduce the result over and over a bunch of diff people can do the test and get the same result good tool for measuring fitness for a general population. How many predictor variables are there: pv = something you measure to put into the equation.
