1-Review of concepts Pan 1: State CIT and ELM. Explain
in details, Aside from one being a parameter estemate and
one being the true population value, what is key, essential
difference between Beta and Beta ? (What does the hat
signify beyond the fact that the parameter is estimated?)
Derive the OLS estimator of Beta0 and Beta1 in the SLRM
What is the generic (textbook) interpretation of the
parameters? State OLS Assumptions A1-A3 for SLRM
(Simple Linear Regression Model), and provide discussion
of the meaning, Importance and relation of each with
Biasedness and efficiency of Beta1. State the Gauss-
Martov Assumptions A1-A4 for SLRM, and provide
discussion of the meaning and importance of each. What
are the Important factors that will change R-Squared, SER
and variance of Beta. Discuss the use of indicator dummy
variables (those which take a value of zero or one) in the
regression contest; particularly, discuss how these would
be used in different contests where there are only two
possible groups to dummy for (male/female in the wage
example) and the interpretation of coefficients attached to
such variables. Discuss and Interpret regression
coefficients based on Stata output tables. Interpret every
single part of the STATA output. You should be able to
calculate missing parts of a STATA output table i.e. the T-
statistics, P-values, R-Squared, and so on.
Solution
there will be many actions and condition influence to
changer R and Beta
