RCBD with missing data using regression

Example 1: Repeat Example 1 of RCBD using Regression with the data on the left side of Figure 1; i.e. the cells C4 and F6 are missing.

The coding is performed in the exact same way as shown in Figure 1 of RCBD using Regression (see the right side of Figure 1 for details).

We perform the regressions as described in RCBD using Regression (see the top part of Figure 2) to obtain the RCBD results shown in the bottom part of Figure 2.

Observation: In the case of one missing data element, the analysis using regression is not likely to be identical to that using the imputation approach described at RCBD with One Missing Data Element.
