The purposes of this exercise are: Test if Y is a valid prediction for X at each time point Test if Y is a valid prediction for X over all time points Find the time points when Y is the best predictor for X I understand basic statistical concepts, but I’m not very familiar with statistics in general, so you’ll have to explain the results of the statistical tests. ...

I have a script I wrote in C# for another program that I want to be ported over into R. I script I wrote in C# probably isnt optomized and its written using classes from another program which are pretty easy to learn/understand but perhaps not clear to everyone. Basically it performs some functions on pieces of the time series data, returns results in a table and then loops over and does it again on the next sequence of time series data (ie does a function once a month, stores the monthly value of the function in a row and then goes onto the next month) I will provide the C# script and a high level documentation / easy language of the script for candidates that are short listed and then I will ask for your feedback in terms of ability to re-code in R. If the job goes well, I have 2 or 3 other scripts I need done as well along with some other more complex analysis. Preference will be given to those who have shown ability to work with time series data in the past (xts) and/or bioinformatics (sequence data analysis)

I am looking for a person that will guide me how to train from plain text so called: 1. semantic langauge model http://cmusphinx.sourceforge.net/wiki/semanticlanguagemodel I am familiar with tools like SRILM, IRSTLM or KENLM but till now I trained only normal models. I need guidance how train semantic LM from normal textual data like http://opus.lingfil.uu.se/OpenSubtitles2016.php Data pre-processing also should be included in the guide. The resulting model should be in ARPA format if possible

We are looking for an experienced statistician who can extract all the stated statistical methods and all the statistical assumptions from a scientific text that were tested before a given method was executed. ... You are given an annotated PDF file, where most (but maybe not all) of the statistical terms are underscored. Using this PDF, for each method and assumption to be checked, please report all your findings in a text file which has the same name as the original PDF file in the following format: (comma separated, the ID can be found in the PDF file next to the annotations) Method Name1,Method1 ID,Assumption1 Name,Assumption1 ID Method Name2,Method2 ID,Assumption2 Name,Assumption2 ID .... e.g. ... - The same applies to statistical assumptions: repeat them for every statistical method they are associated with

It's required to prioritize a series of diagnoses based on a fuzzy factor, for it, upworker must define the formula to apply or create a factor. I have the input variables and decision rules, but I need help to create the distance between values. For academic subjects it is imperative to use fuzzy logic methodology and the results can be reproduced in a web application.
