Repeated observations[edit] In this approach two (or maybe more) repeated observations of the regressor x* are available. pp.7–8. ^ Reiersøl, Olav (1950). "Identifiability of a linear relation between variables which are subject to error". One example is round-off errors: for example if a person's age* is a continuous random variable, whereas the observed age is truncated to the next smallest integer, then the truncation error check over here

Moving walls are generally represented in years. This is a less restrictive assumption than the classical one,[9] as it allows for the presence of heteroscedasticity or other effects in the measurement errors.

The necessary condition for identification is that α + β < 1 {\displaystyle \alpha +\beta <1} , that is misclassification should not happen "too often". (This idea can be generalized to JSTOR1914166.

For exaample, if you want to find the area of a square and measure one side as a length of 1.2 +/- 0.2 m and the other length as 1.3 +/-

The "true" regressor x* is treated as a random variable (structural model), independent from the measurement error η (classic assumption). Biometrika. 78 (3): 451–462.
