Write out the steps for one model selection technique
(backward/forward-elimination with the R-squared,
backward/forward-elimination with the p-value approach, etc.).
1. What is the difference between forward integration and
backward integration?
a. Backward integration involves distribution and sale;
forward integration involves raw material production.
b. Both involve adding value after a product is
manufactured.
c. Forward integration involves distribution and sale;
backward integration involves raw material production.
d. Backward integration involves stripping value at each
stage; forward integration adds value at each stage of the
chain.

A palindrome is a word or phrase, which reads the same backward
or forward. Write a program that prompts the user for a string of
characters terminated by a period and determines
whether the string (without the period) is a
palindrome.
IMP:
Assume that the input contains only letters and blanks.
Assume also that the input is at most 30 characters long. Use an
array of characters of size 30 to store the input!
Disregard blanks when deciding if the...
Arthur Lewis has a model in which the surplus labor is moved out
of the backward agricultural sector and productively employed in
the modern industrial sector. This process is known as modern
sector enlargement. Do you think that this process is capable to
deal with the problems of poverty and income inequality in all
developing countries? You may argue for or against the Lewis
Model.

1. Under which model of sexual selection is sexual conflict
responsible for the evolution of male ornaments or display
traits?
Select one:
a. Run-away sexual selection
b. Chase-away sexual selection
c. Both run-away and chase-away sexual selection
2. Under both run-away or chase-away sexual selection models, a
mail display trait will evolve to become increasingly exaggerated /
extreme, until...
Select one:
a. It is halted from further exaggeration by natural
selection
b. female preference changes in the opposite direction
c....
Choose the FALSE statement:
A) Based on principles of artificial selection, dairy
farmers should be able to change the genetic makeup of their
livestock so that new generations evolve to produce more milk.
B) Based on a comparison of their structure, the wings of bats
and dragonflies can be considered to be homologousstructures, and
thus, products of divergent evolution.
C) Lyell and Hutton‘s observations that slow geological changes
gradually shaped the earth provided Darwin with the idea that
Nature could...
1.What is specification error?
2.What are the criteria for model selection for an empirical
analysis?
3. How will you estimate parameters in case of inclusion of
irrelevant variables?
4. How would you detect that a model is overfitted?
(P.S. - please answer every part)
