    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.

    BASICALLY :- A simple program (on Mac) to take multiple .xlsl files (examples attached) and to strip out one column (a twitter handle), attach a &quot;@&quot; at the start of each, and to pump out the names as .csv files. No usernames to appear twice, so must dedupe and also check against a list of usernames already in existence (BLACKLIST) Needed ASAP (5 days ish). MUST be installed + testedIN MORE DETAIL:to be installed on 2 Mac machines and to do the following:1. IMPORTING DATA:An &quot;IMPORT&quot; button at the top of the data table, will bring up a window allowing selection of several files at a time in the attached xlsx format (there will be only one worksheet per file and the worksheet name may vary so please do not specify a particular worksheet name in the code). Files may contain up to 100,000 records each with sizes up to 40MB. Please show a progress bar with estimated time whilst the following is carried out:a) Check each file to see if it will import successfully (some files may have errors). If there are corrupt files, stop the import and notify the user of the unsuccessful filenames.b) Import &quot;screen name&quot; column and add an @ to the beginning of each entry in this fieldc) Import &quot;location&quot; columnd) Add a third column for &quot;filename&quot; where each record is tagged with the portion of the filename to the left of the first space. Eg. a file named &quot;Blacklist 1.xlsx&quot; would go in as &quot;Blacklist&quot;e) Add a fourth column for &quot;Blacklisted?&quot; with a Y or N value. In the first instance, if the filename column = Blacklist (not case sensitive) this should be a Y, otherwise for newly imported record his should be an N.f) all the other columns are not relevant, so please don&quot;t import them if database will run less efficiently.g) Check &quot;screen name&quot; against records that already exist in the database and delete duplicates. Clarification: - records already existing in the database will take precedence and remain, whilst new incoming duplicates are deleted. - If 2 records with identical screen names are imported at once from separate files, only one instance will remain, matters not which.2. VIEWING + EDITING DATAThe default view in the application should be a table of the data, which can be sorted, filtered + edited in the following way:a) Ability to &quot;clear all&quot; data, with an added &quot;are you sure?&quot; control after pressed.b) Ability to do &quot;contains&quot; search (not case sensitive) at the top of any one of the columns, where if that search is left blank the default will be for all records to appear (subject to the filters on other columns).c) Ability to sort by clicking on the header of any given column.d) and to edit cells3. EXPORTING DATAThe user should be able to specify an export file length to dictate how many records appear in each exported file. The default should be set to 5,000, but the user can change it to whatever they like, then press an EXPORT button with the following result:a) Several csv files of the specified file length would be created and saved to a specified folder.b) They would contain only the &quot;screen name&quot; column (with an @ at the beginning as per the earlier instruction)c) They would be named sequentially according to the filename column, whatever appears in the &quot;location&quot; search field and the file length. Eg if someone had loaded in one file named &quot;Cribs and one named &quot;Bastille&quot;, then searched for &quot;london&quot; in the location search and 5000 as a file length, in the search terms, finding 11,000 bastille records and 7,000 for cribs, the resulting files would be:Bastille-london-5000-1Bastille-london-5000-2Bastille-london-5000-3Cribs-london-5000-1Cribs-london-5000-2If nothing is specified in the &quot;location&quot; search field, the resulting files would be named and exported with only the file name and length. Eg.Bastille-5000-1Bastille-5000-2Lastly, every record that is successfully exported in this way would automatically have its &quot;Blacklisted?&quot; column on the database changed to Y.

    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).
