Lab: EViews Exercises
1. Consider the subsample of recent college graduates (within 10 years, assuming an individual graduates from undergrad at age 22) who live in Southern California.
a. Record the number of observations in the subsample.
b. For wages, record the mean, standard deviation, skew and kurtosis.
c. Create standardizations (z-scores) of the variables: hours. Display the resulting "histograms and statistics" (from Eviews) next to those for the unstandardized versions.
2. Construct binary (indicator) variables for people who are Caucasian and for people who have at least a bachelor's degree, and then use N-way tabulation.
a. White people (Pr[A])
b. Persons with at least a bachelor's(Pr[B])
c. Persons who are white and have at least a bachelor's (Pr[A & B])
d. Persons who are non-white and have at least a bachelor's (Pr[not A & B])
e. Persons who are white or who have at least a bachelor's (Pr[A or B])
f. The proportion of white peopleamong the persons who have at least a bachelor's (Pr[A | B])
g. The proportion of non-white people who have at least a bachelor's (Pr[not B | not A])
3. Clear your subsample. Restrict your sample to people working at least 40 hours per week (no other constraints). Construct and compare the "histogram and statistics" of wages of White people, Black people, Asian people, and American Indian/Alaskan Native people. Display the four histograms next to each other.
4. The standard distance between two data sets ?? and ?? is defined as: |x‾ - y‾| / √[(nx - 1) sx2 / {(nx - 1) + (ny - 1)} + (ny - 1) sy2 / {(nx - 1) + (ny - 1)} (Notice that the denominator is the square root of a weighted average of the two variances.) Use any combination of any variables (except wages) in the entire data set to create a subsample that is (i) most similar to you personally (or perhaps as you predict yourself to be in a couple years), but that (ii) contains at least 8 observations (i.e. n ≥ 8). (There will be many correct choices; just be specific about what your subsample is.) Do this a second time, but with a different group that also meets conditions (i) and (ii). Calculate the standard distance between these two groups, and between each of them and the BRG. (You will probably need to do this by hand; I do not know of any Eviews function that computes this distance directly, although it is embedded in more complex statistical operations.)

Determine a suitable drainage scheme for the new road
: Choose a vertical alignment for your horizontal alignment so that it contains some cutting and some fill sections tying into the existing grades at the ends of the project. A flood crossing is to be considered for the crossing at 390 metres. Provi..

Implement the body of the createstars method
: In the body of the loop, generate random x and y coordinates. Set the color to white and then paint a filled oval with a width and height of two pixels.

Which areas do you feel are most effective within culture
: Which areas do you feel are most effective within the Culture? Explain why you have come to these conclusions. You have to create a thread of not less than 350 words

Discuss about the cost estimates for project resources
: write a 1-page summary document explaining any relevant facts about the project duration, number or type of resources, critical task sequencing, or how duration estimates were arrived at, and any financial implications (for example, budget or cost..

Record the number of observations in the subsample
: ECON 15A- Record the number of observations in the subsample. Create standardizations (z-scores) of variables: hours. Display the resulting "histograms and statistics" (from Eviews) next to those for unstandardized versions.

Create stars of random brightness
: Using the same value for all color components ensures that the resulting color is a shade of neutral gray. Use this new random color for painting the stars. Make sure to generate a new color for every new star.

Create a new vector with some arbitrary direction
: Test. If all went well, the rocket should drift all by itself when the scenario starts. Don't make this initial drift too fast. Experiment until you have a nice, slow initial movement.

Define philosophical anthropology
: Define philosophical anthropology and compare the psychological and theological understandings of philosophical anthropology. Identify several distinct contributions offered by psychology that are absent (not offered in detail) from Christian theo..

Use of the term behavioural economics
: Use of the term "behavioural economics" has been criticized on two accounts: redundancyand ambiguity. Briefly explain these two criticisms and determine whether they have anybearing on the merit of this line of economic study.
