WebThe linearity assumption can best be tested with scatter plots, the following two examples depict two cases, where no and little linearity is present. Secondly, the linear regression analysis requires all variables to be multivariate normal. This assumption can best be checked with a histogram or a Q-Q-Plot. WebLinearity refers to the relationship between the final analytical result for a measurement and the concentration of the analyte being measured. This distinction is relevant because a plot of analyte concentration versus measurement signal from the instrument may not be linear. The concept of “linearity” is not separately designated by CLIA.
