Introduction to Econometrics
What is Econometrics ?
Econometrics may be defined as
the social science in which the tools of economic theory,
mathematics & statistical inference are applied to the analysis
of economic phenomena
Econometrics attempts:

Multicollinearity
Why does the classical linear regression model assume
that there is no multicollinearity among the Xs?
If multicollinearity is perfect then the regression
coefficients of the X variables are indeterminate and
their standard errors are i
11th Five Year Plan and Inclusive Growth
The concept of inclusive growth was initiated
during 11th five year plan strategy.
The performance of growth rate in 9th plan (1997-98 to
