The results of the values provided above confirms the model to be robust
and reliable.
Exogenous Observations: While considering different variables of the
model we came across several variables that couldn’t be included due to
several issues like modelling problems, lack of adequate number of
observation and etc. Those variables are Minimum Support Price (MSP) of
food grains, Issue price and economic cost of production of food grains,
food stock of food grains, government outlay on agriculture and
agricultural research and development. On the basis of these variables
following observations are being made which are exogenous to the
existing model of the paper.
