Types of Regression Analyses

/in /by

There are two major types of regression analysis—simple and multiple regression analysis. Both types consist
of dependent and independent variables. Simple linear regression has two variables—dependent and
independent. Multiple regression consists of dependent variable and two or more independent variables.
How does a multiple regression compare with a simple linear regression?
What are the various ways to determine what variables should be included in a multiple regression equation?
Compare and contrast the following processes: forward selection, backward elimination, and stepwise
selection.
Justify your answers using examples and reasoning. Comment on the postings of at least two peers and state
whether you agree or disagree with their views.

Evaluating trainers

/in /by

How is training different from education and development?

Give workplace examples and cite ideas from your text (add page #) and other sources per course outline (cite source).

What is the role of the trainer?

Have the trainers you’ve been trained by exemplified that role? How or how not?

Again, use workplace examples and integrate ideas from your text (cite page #) and other sources (cite URL or source).

Your response to each question must be 200 words long, and must demonstrate clear, insightful critical thinking.

Please read the attached documents carefully and answer the two parts of the assignment..that is part I and part II

/in /by

Part 1: Inventory Simulation Game

Assuming that you knew the actual demands in advance, improve your ordering schedule.

Hint: The optimal ordering policy has zero shortage costs in every period, AND an ending inventory of zero in the last time period. And such a policy has the maximum annual profit of more than $5200. Improve your initial solution such that you have an annual profit as close to this number as possible.

In 250 words, explain the ordering policy that you could improve to. What are the solution properties that you can observe?

(Also, email your Excel file to me separately before the deadline.)

Part 2: Beer Distribution Game: (The instructions to access your data in the simulations are provided as another attachment to the email.)

1.Discuss the decisions you have made in each of these games. Do not blame other people in the game. Analyze your own performance in the context of each game and

critically evaluate your own decisions. What were good decisions vs. bad decisions? If you were to play the game again, what changes would you have made?

  • For all games and roles you played, explain your observations about the degree of fluctuation in the order quantities and inventory/backorder levels. What do you think contributes to these fluctuations? What are the implications of this effect for each role you played in the game?
  • Compare the effects of your decisions in each different role to the other players in the game.
  • Explain the changes in your personal strategy for making ordering decisions in each game and role you played.
  • Explain the impacts of information sharing and lead time variation on your performance.
  • Discuss your group strategy, level of collaboration and associated impacts on your total costs.

You are being graded on critically looking at your own performance by analyzing graphs and data. You should refer to the plots and data in detail when explaining your decisions.

Fossil Records history assignment help

/in /by

fossil records

Fossils are always cited in support of evolution, but as Darwin admitted, “Geology assuredly does not reveal any such finely-graduated organic chain; and this, perhaps, is the most obvious and serious objection which can be urged against the theory. The explanation lies, as I believe, in the extreme imperfection of the geological record.” His good friend Huxley warned him that he had burdened his theory unnecessarily by insisting on the idea of slow, gradual change.

Consider the Chapter readings in The Origin. Why is the fossil record so imperfect? What kinds of evidence does Darwin cite? Do you think Darwin makes his case? Why or why not? What evidence has come to light since Darwin’s time that supports the idea that organisms have changed slowly and gradually? What are some of the strengths and weaknesses of relying on fossil evidence? In your discussion, include information on how difficult it actually is for remains to be fossilized. What conditions must be met for fossilization to occur? What traits are best studied this way? What information is not provided by fossils?

As the answers to all of these questions may not necessarily be in your assigned readings, you may need to “go digging” for information (on the WWW for example). Be sure to cite the sources of your information in your postings.

This post needs to be substantial and well written with at least 3-4 paragraphs, all  sources must be sited and useable. Please be careful as to not use .com websites. I prefer articles as my source or books and pappers writtn
