based on the hypothesis below answer the following questions please.

Hypothesis: Water will diffuse from a region of high water potential to a region of low water potential when both solutions exhibit a water potential gradient and are separated by a semi-permeable membrane because water movement occurs along the water potential gradient.

  1. What is your independent variable? (what you are manipulating or testing)
  2. What is your experimental group?
  3. What is your control group?
  4. Is your independent variable continuous data (e.g. time, distance, length, etc.) or discontinuous data (e.g. categorical data like color, binned data like small, medium, large categories, etc.)
  5. What will be similar about how you will treat your experimental and control groups? (i.e. what are your controlled variables)
  6. What will be different about how you treat your experimental and control groups? (i.e. what is your experimental variable)
  7. What is your dependent variable and how will you measure it? (the outcome you are measuring; the duration, interval of sampling, unit of measure, etc.)
  8. What do you predict will be the relationship between your independent and dependent variables? (i.e. what do you think will happen if your hypothesis is supported, not supported?)
  9. Sketch or describe a graph of your expected results if your hypothesis is supported. Remember that independent variables are plotted on the x-axis and dependent variables are plotted on the y-axis.

Financial Economics – Leverage and Diversification Economics Assignment Help

Question 3 – leverage and diversification

Imagine you have a risk-free asset, whose return is 0, and two risky assets with μ1=0.1, σ1=0.1, μ2=0.2, σ2=0.3, ρ1,2=0. Once we compute the tangency portfolio, we get that it has μT=0.118 and σT=0.098 (you do not have to compute it).

  1. What are the mean return and standard deviation of the portfolio on the efficient frontier as a function of the share of the risk-free asset in the portfolio?
  2. Assume that you are rational and risk-averse, so that you choose portfolios along the efficient frontier from the question above. Moreover, assume that you have leverage in your portfolio of the following sort: you sell short (borrow) so much of the risk-free asset that its share in your portfolio is -0.5. What is the mean return and standard deviation of your portfolio?

You wake up next day and you see that the only parameter that changes is the correlation between your risky assets: it decreased to ρ1,2=-0.5. This led to the change in your tangency portfolio, which has now the following parameters μT=0.122 and σT=0.073 (notice what happened with these two parameters).

  1. In order to earn the same return as in question 2, what share of your portfolio should be in the risk-free asset? Does your leverage increase or decrease? What happens with the variance of such portfolio?
  2. In order to keep the risk (variance) of your new portfolio the same as in question 2, what share of your portfolio should be in the risk-free asset? Does your leverage increase or decrease? What happens with the mean return of such portfolio?

I provide all the information in the file. please read carefully, and I also provide one ipynb that i did so far.

Tasks Data Understanding: Conduct a thorough EDA to gain a better understanding of the given data and business objectives. This includes but not limited to: checking/dealing with missing data and outliers if any; top popular items sold and their characteristics; recommendation and rating patterns across departments and product types. buying and reviewing behavior of different age groups, etc. Carefully present your analysis and findings in your report.

Build a Benchmark Model to Predict Recommendation: Build a simple logistic regression model to assess the feasibility of recommendation prediction and establish a baseline model. For this task, you are required to build your baseline model using bag of words of the review text only. Use scikit-learn’s logistic regression model with “solver” set to ‘liblinear’ and all other parameters set to default. Use scikit-learn’s CountVectorizer with “max_features” set to 500 and all other parameters set to default. You need to choose appropriate evaluation metrics and model evaluation strategies to validate your model. Present your analysis and discuss your findings. Improving Your Benchmark Model: You are required to make attempts to improve the performance of your benchmark model as much as you can. You should consider using more advanced feature engineering techniques and adding extra features to rebuild your model. Your choice of decisions should be justified based on the evidence from the data and accompanied by detailed explanation. You must properly validate your model and optimize appropriate hyperparameters that apply. Simply building a model without any consideration of validation and optimisation does not meet the minimum requirements. You should demonstrate evidence of your efforts and you will be assessed based on the depth of your exploration. Provide a summary of what has worked and what has not. Report on your improved models and make comparisons with the benchmark model. Note: You must use logistic regression and no other models are allowed for this task. Interpreting Results: Decide on your best model and provide analysis and interpretation of its behavior. For example, you may report on the features associated with positive/negative recommendation. For your interpretation, you should focus on identifying general rules that might be useful for the company to improve its business in the future. Final Test Results: Finally, apply your best model on the test data. You are asked to report the classification results on the test data. Save your results into a csv file containing two columns, one for the Review Index (ID from product_test.csv) and the other column Recommended for the predicted labels (1’s or 0’s). An example file of test results test_results_example.csv is also provided. Name your file as GroupID_Test_Results.csv. The results on the test data will be assessed to decide your group performance among the entire class (group competition!).

Library Research Assignment

You now have change programs in various stages of implementation at a large number of the 60 companies in your portfolio. Some of the companies are doing quite well, and others are stalling or are nonresponsive to the change initiatives being implemented. You have a feeling that there is resistance that is taking place, and you want to roll out some new concepts and ideas to help the leaders of these companies handle this resistance. A number of these leaders have asked you for ideas that would help them understand the resistance and to perhaps create action plans to address the issues involved. You presented a set of possible issues, which has prompted the line managers to ask for more specifics to increase the success of all the change initiatives.

Complete the following:

  • What is the relationship between change drivers and impediments to change in an organization?
  • Explain different external and internal change drivers, and describe their impact on people in an organization.
  • What are the applicable models and strategies to overcome resistance to change?
  • How does your current set of recommendations demonstrate either a reduction in the resistance to change or the need to adjust some of the change drivers?
  • What are at least 5 specific recommended steps that can be taken in the present situation described?

Note: You have the choice of the following delivery options for this assignment:

  • A paper of 1,800–2,200 words

  • Visio flow charts with an accompanying script of 2,000 words
  • Viseo with accompanying script with 2,000 words (plus or minus 10%)
  • Smart charts

Note: Use a minimum of 1 chart in your analysis or description of a model or strategy being recommended, and use 1 flow chart to visually show the stages in your recommendation.

Be sure to use APA formatting and valid graduate-level references.

Please submit your assignment.
