I can't test this solution at my office due to administration constraint, although it is doable, as mentioned in R help document, Quotation bit versions of Windows run bit executables under the WOW Windows on Windows subsystem: they run in almost exactly the same way as on a bit version of Windows, except that the address limit for the R process is 4GB rather than 2GB or perhaps 3GB The disadvantages are that all the pointers are 8 rather than 4 bytes and so small objects are larger and more data has to be moved around, and that far less external software is available for bit versions of the OS.
This CSV splitter allows you to split your large file into several smaller files either by number of lines or by max pieces,The amazing point of it is the smaller files keep the original header of the big csv file, very cool.

Data massaging is not fun, what makes us more upset is different data providers have their own data format, name, code, etc. I didn't understand why they do business like that but now I get it, similar as those cell phone manufacturers have distinct chargers and plug-in, not because it's hard to standardize, but a way to impose customers to use always their own products.
As always, I have been looking for guest writers. Tags -isin , cusip Investment banks and the World CupThis is a news tip that might be of interest sent by Anthony Goldbloom, thanks. In the lead-up to the world cup, Kaggle invited statisticians and data miners to take on the big investment banks in predicting the outcome of the World Cup.
In total, 65 teams participated in the Take on the Quants challenge. The betting markets fared better, finishing 16th. The winner of the competition was Thomas Mahony, an Australian economist. His strategy correctly tipped Spain to win, the Netherlands to finish second and Germany to finish in the top four.
The next big question is whether Kagglers can also outperform the quants in forecasting financial markets we won't have to wait long to find out, as Kaggle is currently hosting a competition to predict stock price movements. Tags -quant , world-cup Send SMS in MatlabRos is a colleague of mine in the same office, his main research is empirical analysis of different option pricing models, and as a result, he often use several computers on different desks to run his matlab codes, which is time-consuming and not rare to last 2 or 3 days.
So he has to come back office frequently to check which computer has finished the task. It sounds boring, why not write a small script to send SMS message to you automatically when your matlab stops running? Send Text Message to Cell Phone is such a great file I found recently, bascially what it does is to send email via sendmail function of Matlab from your gmail box to your cell phone carrier, and then your cell phone carrier forwards the email to you as a text message.
Do let me know if you are aware of a better alternative. Possible errorDepends on your Matlab version and firewall setting, you may notice the following errors: 1,??? What you shall do is too add an exception and let your computer know this action is safe.
Ros, you don't have to check computers one by one. Sounds useful? Tags -matlab , sms Excellent R Code Format PackageI have been looking for this type of package for several days, and luckily found it today.
Unquestionable R is powerful, however, R programming is unfriendly as far as I concern, mainly due to the lack of format shortcut, which makes the R codes rather ugly. FormatR is the package for tidying R source code, although it is less convenient to use than the straightforward shortcuts in Matlab, this package is good enough for me, what is it for? Show him your hundreads of lines code, point to the lines, explain what the arguments and outputs are?
No, it is not a smart way since you are supposed to introduce in a few short sentences. As the old saying goes: a picture is worth a thousand words, so in a same logic, a GUI is worth n thousand words. It becomes even worse in R language, to be honest, I hate the graph plotting in R, terribly unflexible compared with in Matlab. Luckily I came across a good R GUI package named "fgui", it does as its description: Rapidly create a GUI interface for a function you created by automatically creating widgets for arguments of the function.
Very nice indeed, after playing for half an hour, it is simple to use, especially when what you need is just a basic GUI demonstrating to others a rough idea. One line code is enough. More advanced GUI is possible by adding more lines. So you are a quant-gambler? Traders, analysts, investors and hedge funds are always looking for techniques to better predict stock price movements.
Knowing whether a stock will increase or decrease allows traders to make better investment decisions. Moreover, good predictive models allow traders to better understand what drives stock prices, supporting better risk management. The results of this contest could have a big impact on the finance industry. QuotationCompetitors will be provided with intraday trading data showing stock price movements at five minute intervals, sectoral data, economic data, experts' predictions and indices.
We have provided a training database to allow participants to build their predictive models. Participants will submit their predictions for the test database which doesn't include the variable being predicted. The public leaderboard will be calculated based on 10 per cent of the test dataset.
The submission deadline is October 10th Final results will be announced on October 12th. A good debug tool, command or even habit will definitely improve your work efficiency, shorten working hour, and enjoy more the world cup. When it comes to Matlab and R, I have to say the debugging in Matlab is straightforward but is more comprehensive in R.
Tags -debug Forex Market Strategy Guide: Scalping There are multiple ways of profiting in forex, including swing trading or trend following. However, scalping is the method with the shortest trading periods. With this method, traders usually open a trade for minutes, or 5 minutes at the very most. The idea is to benefit from short fluctuations in the market. This series of articles will serve as a guide for scalping, but for the purpose of introduction, we can ask what makes this strategy popular and effective.
Many of these considerations will then serve as the topics of further articles. The first major reason for scalping is perceived safety. Scalping has a far shorter time frame than the other forex methods, and many traders argue that this limits their exposure to the market.
Of course, this limited exposure leads to a second major characteristic of scalping-a large number of trades. Some scalpers may open and close as many as several hundred trades within a single trading day. This points to one of the major challenges for this style of trading. Since the number of trades is extraordinarily high, scalpers must find forex brokers with low transaction costs and fees.
Before considering this style, make sure that your broker's commission structure allows for you to be profitable. A third characteristic is the fact that scalpers rely on some type of leverage. The profit from each trade is generally quite small, and even with a huge number of orders, the results would hardly be worthy of the effort. Depending on the amount of leverage you use, this can eliminate any real security. In spite of their arguments to the contrary, scalpers can lose a day's work in a few bad transactions.
A fourth characteristic of scalping is that it is generally a full-time endeavor. This is a significant limitation, since the majority of forex traders only do it in order to supplement their income.
Scalping requires constant and undivided attention. If you decide to use this strategy, expect it to dominate your time and efforts for as long as you are trading. It is generally best to set aside an extended period of time and eliminate any other distractions. This is unworkable for many traders, though when a scalper finishes for the day, his exposure is finished as well.
Some scalpers try to eliminate this problem by automating the process. In recent years, a vast number of robots and software automation kits have become available for scalpers. Unfortunately, most of these are unproven, and many make wild claims that stretch far beyond plausibility. Still, there is a real benefit in automating certain parts of the process. For instance, you might use software to execute redundant tasks like stop-loss, take profit and other orders, while doing the analytical tasks yourself.
In this limited role, the automation can be a significant help by allowing you to execute more trades with less drudgery. Scalping is a workable strategy if you know what you are doing and are willing to dedicate your full time energy to forex trading. Unfortunately, too many beginners try scalping based on the assumption that they can avoid risk.
As any experienced investor knows, risk accompanies any genuine financial opportunity. After several months of practice, and with plenty of education, scalping is a great way to enter the forex markets.
This guide will tell you some of the main things you need to know when getting started. The first step in any guide on scalping is understanding how scalpers actually make money. What does a scalping strategy look like in daily practice? We already mentioned that scalping involves entering and exiting the market in short time spans.
But what guides the choice to enter or exit? Actually, this strategy works on the basis of careful analysis and timing.
