AS 604 LINEAR MODELS                       (2L+0P) I

Objective
The students would be exposed to the theory of linear models, estimation of variance components for unbalanced data and advanced techniques for analysis of data in agriculture.

Theory

UNIT I
General Gauss Markoff set up, Gauss-Markoff ’s theorem, Aitken’s transformation. Theory of linear estimation, test of hypothesis in linear models. Analysis of variance, partitioning of degrees of freedom. Restricted least squares. Special cases of one and two way classifications (including disproportionate cell frequencies and interaction, cross and nested classifications).

UNIT II
