and publish it to others. just like using a word program, this degree of convenience is far from matlab. For example, if we want to capture some data on the Internet, it is troublesome to use matlab, and using python is extremely simple. Python can greatly accelerate the automation and simplicity of our research. All we need is to study python for a while.

Third, python replaces SAS. In fact, python has no obvious advantage in this aspect. The statistical function is inferior to SAS, but the advantage of using python is that we do not need to learn the SAS language again, especially for financial engineering majors, there is not much time and need to learn SAS. We are not engaged in professional data statistics. Most of the functions of SAS can be implemented in python, but it is more difficult to implement than SAS. For financial engineering p
ability to break through the bottleneck, can make the entire industry scale start to grow exponentially.
Privately, it is only by understanding the origins of the era of big data that we can put our position in the tide of times.
Milestone 2:r/python
Two years ago, we were discussing "what software should be used for statistical analysis". There were many options at the time, Spss,sas,r,python,excel,eviews,stata,c++,java ... The number is not counte

This part of the work needs to do a lot of statistical work, you want to do a neural network, or SVM, or Bayesian learning, and so on, even if simple as linear regression, in the final analysis is statistical work, a good statistical software can make your productivity greatly incre

Other secondary information:(gives a calculation of how to use R)This English document gives the algorithm in Excel, but I don't see

Quantitative investment involves a lot of code practices: model development, model practices, and model correction.

1 the ACF and PACF diagrams are very important two concepts in time series, if the time series are used to model, trade or predict. These two concepts are necessary.2 ACF and PACF are: autocorrelation function (coefficient) and partial autocorrelation function (coefficient).3 in many software such as eviews analysis software can call up a sequence of ACF and PACF diagram, as follows: 3.1 Sometimes this picture is lying, but this is not important, any

math.I've had a similar puzzle before, so I've been talking to a professor, and that's the answer I got.Of course I'm not trying to make excuses for every year I'm calling to learn Python, and R Dafa is good. One advantage of R is that it is written by statisticians, and the disadvantage of R is that it is written by statisticians.In my definition, R/python/matlab, is basically can replace each other, the more difficult to choose the more the explanation can be. When I was repairing the ML, I a

Artificial sweeteners can be used instead of sugar.Even with diabetes, you can include some sugar in foods and baking. The trick is not to overdo it, by keeping sugary foods and drinks for a occasional treat, and finding alternatives where You can. Try using artificial sweeteners when sweetening food and drinks at home.Ten. HydrateDrink 8-10 cups of water a day, milk,
is my answer.
Of course, I am not shouting for every year that I want to learn python, and I haven't made any excuses yet, as well as R. One advantage of R is that it is written by statisticians, and R is also written by statisticians.
In my definition, R, python, and matlab can basically replace each other. When I was repairing ML, I asked the teacher which one is the most suitable. The teacher can answer all the questions. Regardless of the statistical measurement or time series, I have alwa
, the regularity of the data (that is, whether it is the above mentioned return), 2, each method is used properly (to find the most matching fitting equation ). If the regression using the data of each method is given an appropriate fitting equation, I think the differences between the same data fitting equations are smaller.Of course there are some differences between various methods. Therefore, even if you meet the above two conditions, the fitting equations may not be exactly the same. As lon
