The regression of on X will in general have non-zero coefficients everywhere and the estimate of b will be biased in all ways. In particular, what if the data was censored in the sense that only observations of Y that are not too small nor too large are included in the sample: MIN (Yi(MAX.

At the same time additional assumptions make the OLS estimator less general. Derivation of the OLS Estimator. The need for assumptions in the problem setup and derivation has been previously discussed. Only a brief recap is presented. Assumptions A, B1, B2, and D are necessary for the OLS problem setup and derivation.
