    I have a fminsearch routine in MATLAB which I have already coded and tested. I need to do 2 tasks:(1) Write a program that randomizes the initial value and repeats estimation many (~100) times. From this, I will the estimates with highest fval.(2) Write a bootstrap program for the standard errors of the chosen estimates using this code: code and .m files are attached. Please take a look.I am following a strict deadline, so I will award project quickly and hope to have it done quickly as well.

    Hi,I need to convert an existing statistical algorithm into a functional R code. The algorithm deals with, generally speaking, a version of survival analysis. The input for the analysis is simple distribution of &quot;time since the event&quot; dates (in our case here - times since forest fire) for forest patches of particular size. In summary, the algorithm does three things: (1) it identifies various parameter of this distribution, (2) it determines the epochs (periods) with different survival probabilities (in our case here - hazards of burning), using the Bayes Information Criterion to find the optimal number of breakpoints in the distribution, and finally (3) assess parameters of sub-distributions. The project will require good skills in statistics and R. I would like to stress the importance of the statistical experience in particular. In the context of this project, I am a &quot;user&quot;, not a statistician, who developed the method. I attached a text with full details on the algorithm. The attached paper contains two example datasets which should be helpful in testing the code. These will be available to the coder as data files.I also have other texts written by this author with description of the same protocol. Additional texts will be available to the coder selected for the job, however it is my understanding that the attached text should be sufficient. I would like to have the code well documented and, preferably, written as a function so I can easily plug it in into a larger R program. The requested code can take advantage of existing R functions (e.g. BIC estimation) as soon as it can generate the required range of output variables.Finally, I would like to mention that I will need help with similar projects in the future and I am interested in finding a skillful and responsible professional for long-term cooperation.

    Our firm trades in certain environmental commodities such as California Carbon, RGGI (&quot;Regional Greenhouse Gas Initiative), NJ Solar Renewable Energy Credits and others that have certain mandated price (hard or soft) price floors and ceilings to mitigate price volatility. Most entities use a basic black scholes pricing model to price up options in these markets but such models assume a normal distribution of outcomes and do not properly take into consideration certain regulatory limitations such as price floors and banking. We would like to engage you to construct an option pricing model in excel with an easy to use interface for us to price and produce all the relevant greeks taking into consideration the differences in the market. The model should be able to be adjusted easily by the end user such that we can adjust the floor and ceilings or banking rules and probabilities of such events. This shall be a work for hire product where all work product is owned by our firm once produced and all copies are destroyed by the contractor once created. Please submit a project level proposal at a fixed price and with completion expected in the next four weeks or earlier. Ongoing interaction during the project with our firm to make sure the work product is what we need will be required. If the project is completed as requested and of a high level of quality, it expected we would continue with other assignments in the future on a regular basis.

    You have recently landed a job as a hedge fund manager and your first task is toinvest in initial public offerings of companies that operate in the same industry.The hedge fund investment policy states that the investment decision should be basedon a statistical model rather than on personal opinion. As a result, you have to build amodel for estimating the probability of underpricing by taking into account thefollowing data/information: 1) overhang, 2) price update, 3) stock market sentiment,4) underwriters’ ranking, 5) total asset turnover and 6) gearing.The empirical model has to be built on a sample of 25 IPOs that took place during theperiod 2000-2010 (in-sample period). After the models’ coefficients have beenestimated, you are required to perform an out-of-sample testing (i.e. the empiricalmodels’ underpricing prediction ability for upcoming IPOs) on 5 IPOs that went tothe market during 2011-2013.Finally, assuming that you have to construct a US$10 million portfolio of the 5 outof-sample IPOs, you are also required to present results on the portfolio’s first tradingday return when: 1) trying to maximise the probability of underpricing and assignequal weights to the allocation of available capital; and 2) trying to maximise theprobability of underpricing and follow the hedge fund maximum and minimumcapital allocation policy of “allocations should not exceed 35% of the availablecapital, and a minimum of 5% of the available capital should be allocated to all assetsunder consideration”.You should write a report that does not exceed 2,500 words (excl. graphs, tables,footnotes, references and appendices) and hand it in to the senior management teamfor approval. Note that, the report should include information, statistics and graphsthat you deem necessary, but not the actual workings on building the model andfurther testing (the latter should be handed in on a separate excel file where all thecoursework data/information employed should be presented).

    Hello OriolAM, it is me again, Eddie Cooray. You did a project for me about a month ago and I told you I&quot;d have a second one coming up - here it is. The assignment involves 2 questions and the students have to pick one. We&quot;ve picked our question so that&quot;s the question I&quot;m sending you. It is about the effect of education on fertility in Botswana. There isn&quot;t a specific format to this project in the sense that there is no particular set of questions to be answered. When you read the assignment it&quot;ll make sense to you. I have some time regarding the completion of this assignment. However I would like it if it could be completed in 2 days. I realise you may be busy, so I understand if that isn&quot;t possible. But I will pay you more if you can do it in 2 days and do it well - say, $50 extra? If 2 days isn&quot;t possible, I&quot;m okay with 5 days. Thanks and be in touch,Eddie

    HiI would like to get in contact with those who understand mathematics, probabilities, and the world of the stock market terminology. You should be familiar with words like correlation, standard deviation, cointegration and null hypothesis. Your basic programming language should be C#, and you are familiar with other types as well. Of course you are an Excel-expert :-)I can offer long term work if you are the right person. If we get a good match there could be good future possibilities in this.I need you to be available on daily basis, not 7 hours a day, but if you have a full time job somewhere else this will not work in the long run.Please contact me if this sounds interesting. If you have created relevant trading-related stuff I would like to hear about it.As this is for the long term, I prefer payment pr hour, but I&quot;m open for project-salary where that is the best way to go.
