    I need somebody to code a Financial Econometrics regression and generate a statistical output with tables (ideally in R, python also accepted). I will provide the dataset and the model, you will provide the code and explanatory tables with results. Ideally looking for someone with a Masters level in statistics used to working with Financial data. Knowledge of coding linear regressions and providing output tables and basic (non exhaustive, I will write the paper) comments on results are required. It will be similar level to coding a regression of the Fung & Hsieh factor model for analyzing hedge fund performance. Happy to discuss pricing and will give a bonus if it can be done by July 1st. If you are well versed in coding, it should take less than 10 hours.

    We have data already cleaned and ready to be analysed in R. We need someone to provide graphs from our data. The data contains: temperature, humidity and weight datapoints. Taken every 2 seconds over 12 months. We have this data zipped and ready for R. Already in an R file. We now need someone to work with us to analyse the data . For example: We need to see weight increase and decrease over different time periods. We need to see humidity increase and decrease over different time periods We need temperature increas and decrease over different time periods. Before I send any files , I would like to see if someone can assist with this and what the approximate cost would be. The data we have is not complicated, but it is a lot of data. The analysis we need is also not complicated.

    trying to fit linear models in R using relatively large datasets which we now realize is beyond R's natural ability without using something like sparklyr, which we want to avoid. So, we would like to use a batched training approach that merges the results of model training performed on smaller datasets. Using small batches goes MUCH faster and doesn't run out of memory. However, we need a validated process to merge the results by averaging the fitted coefficients from across all batches. We've found this package called MuMInwhich promises to do the averaging for us. However, we need some help to help validate the process, craft an alternative if MuMIn doesn't work as planned, and hand over a working example that we can leverage in our work. The approach we have in m...

    Can you help us find a solution to perform batch training of a linear model in R? We are trying to fit linear models in R using relatively large datasets which we now realize is beyond R's natural ability without using something like sparklyr, which we want to avoid. Will discuss more details in chat. Thanks.

    Create a histogram of the signals (which would yield a 2-dimensional matrix) followed by over time dimension, that would finally yield a 3D- matrix. Then convert that 3D matrix histogram to heatmap.

    Create an R script, which 1. reads the time series (as long back as available) of the single values of the NASDAQ-100 as well as S&P500 index (prices on a daily basis) as a data set into R on a daily basis (e.g. using a suitable R package) 2. plots time series of the price indices of the individual values with the name of the stock and the time axis (X) as well as the price (Y-axis) in one graphic window each (these are then 100 or 500 small graphics in one window, e.g. 5 in one line, which must be able to be scrolled in order to get a quick overview of all price developments on the screen) 3. the length of the time series of the displayed price trends should be globally adjustable (e.g. the last year, the last 5 years etc.)

    To do the software for controlling the ON and OFF sates of a Linear Actuator (5-6 Newton) in relation to the "R" peaks of an EKG of a subject in real time. A look up Table with the ordinal positions of the "R" peaks on which an OFF-ON event will take place is provided OFF Line by an Administrator. The On takes place after a Time Delay TD from the "R" peak in the ordinal position given in the Look Up Table. The OFF comes TA milliseconds later. The TD and TA are given in milliseconds by algorithms 1 and 2. Both are simple algebraic algorithms, on which the independent variables are the distance between predefined "R" peaks, and gender (Male or Female). The EKG signal is provided by a BIOPAC 100 Amplifier. Because we are in different countries, please...

    I will provide a text file of a series of coordinates in (x,y,z) format. This is like the Cartesian plane (x,y), but with a third dimension. Your task is to create a set of code that will do the following things: 1. Read in the contents of the text file to a table, with headers as given in the file. 2. Make the following things the body of a loop: a. One that will convert an (x,y,z) into cylindrical coordinates (r,θ,z) b. One that will convert an (x,y,z) into spherical coordinates (p,θ,φ) 3. Using some kind of loop, use this procedure to populate either a matrix or array that contains the converted values (cylindricals separate from sphericals) 4. After the loop has completed, write each of those arrays/matrices to a separate .csv file.

    We need to calculate the Levenshtein distance with the R package stringdist. However, we have the problem that we do not get a result, but a + appears in the console after entering the command. We have already looked to see if we have forgotten a bracket or something similar, but this is not the case. If we calculate each sentence separately, the calculation works. However, if we add the whole text to the command, the + appears in the console. We require help to get the command to work.
