Question

Suppose you have an n×n additive matrix M with n ≥ 4, and you erase the entries

corresponding to two symmetric entries Mij and Mji in the matrix. Give an algorithm

to infer those two missing values (Mij and Mji) from the remaining data, and prove it

correct.

Answer 1

Here one sample has missing value which is not because of dataset variables but is to simply omit those cases with the missing data and analyse the remaining data.2) Last Observation Carried Forward
