Detailed steps to publish journal articles:

For those who publish a paper for the first time, they don’t know what materials need to be prepared, how to publish it, and they don’t know where to start. In fact, publishing a paper is very simple, it only takes a few simple steps, I believe you will understand soon.

  1. Prepare the manuscript Everyone can write articles, but the articles written may not be suitable for publication, so you can read some papers related to yourself as a reference before publishing. Since it is a paper to be published, you have to put forward your own opinions, verify your own opinions, and summarize your own opinions. Such papers are meaningful. Moreover, the length of the paper should not be too long, and the length of the paper should not be as large as possible. The size of the journal is fixed. Too many words will only increase the workload of the editor. You know, a good paper can greatly shorten the time for publication.
  2. Select a journal and prepare for submission Before submitting a manuscript, you must first choose the journal you want to publish. It is especially important to note that each journal has its own style and characteristics, and you need to filter out journals that fit your thesis field so that it can be published more easily. There are hundreds of journals in my country, and each journal has its own requirements. Generally speaking, the homepage of each journal can download paper writing templates and requirements. Authors can write papers according to the templates and requirements to avoid direct rejection due to format inconsistencies.
  3. Waiting for the results of the preliminary review after choosing a journal, you must submit your papers. Most journals can submit papers through the online system. Special attention should be paid to the journal’s requirements during the submission process. Some journals will require copyright agreements and other materials. Different journals have different initial review time, some require one week, some require one month, just wait quietly.
  4. Modify the manuscript, after the paper has passed the preliminary review, the journal editor will get in touch with the author. The paper will not be passed at one time and requires multiple revisions. The editor will put forward comments and requirements on the manuscript. At this time, it only needs to be revised according to the editor’s requirements that’s it. When talking with the editor in charge, remember to be sincere and open-minded to ask for advice. This will help close the distance between the two people, provide you with some better suggestions, and publish more smoothly.
  5. Payment of fees if you are lucky enough to get to this step, it means that your paper has been submitted successfully. The fee that needs to be paid is to pay the page fee to the magazine, and the fee must be paid in time to ensure the smooth publication of the paper. Of course, if your paper is well written, the magazine will also pay you a certain amount of manuscript fees.

What is regression?


Regression analysis is a mathematical model. When the dependent variable and the independent variable have a linear relationship, it is a special linear model. 

The simplest case is one- variable linear regression , which consists of an independent variable and a dependent variable that are roughly linearly related; the model is Y=a+bX+ε (X is the independent variable, Y is the dependent variable, and ε is the random error ) . 

It is usually assumed that the mean value of random error is 0, and the variance is σ^2 (σ^2﹥0, σ^2 has nothing to do with the value of X). If it is further assumed that random errors follow a normal distribution , it is called a normal linear model. Generally, if there are k independent variables and 1 dependent variable, the value of the dependent variable is divided into two parts: one part is affected by the independent variable, that is, expressed as its function, the function form is known and contains unknown parameters; the other part is Other unconsidered factors and random influence, namely random error.

When the function is a linear function with unknown parameters, it is called a linear regression analysis model; when the function is a nonlinear function with unknown parameters , it is called a nonlinear regression analysis model. When the number of independent variables is greater than 1, it is called multiple regression, and when the number of dependent variables is greater than 1, it is called multiple regression. 

Regression analysis content

The main contents of regression analysis are as follows:

① Starting from a set of data, determine the quantitative relationship between certain variables; that is, establish a mathematical model and estimate unknown parameters. Usually the least square method is used .

②Test the trustworthiness of these relations.

③In the relationship between multiple independent variables affecting one dependent variable, judge whether the independent variable’s influence is significant, and select the significant influence into the model, and eliminate the insignificant variables. Stepwise regression , forward regression and backward regression are usually used .

④ Predict or control a certain process by using the required relationship.

The application of regression analysis is very extensive, and the use of statistical software packages can make various algorithms more convenient.

Regression type

The main types of regression are: linear regression, curvilinear regression, binary logistic regression, and multiple logistic regression.

Types of Data analysis

In the field of statistics , some people divide data analysis into descriptive statistical analysis, exploratory data analysis, and confirmatory data analysis; among them, exploratory data analysis focuses on discovering new features in the data, while confirmatory data analysis is Focus on the verification or falsification of existing assumptions.

Exploratory data analysis

Exploratory data analysis refers to a method of analyzing data in order to form a worthy hypothesis test, which is a supplement to traditional statistical hypothesis testing methods. This method is named by the famous American statistician John Tukey.

Qualitative data analysis

Qualitative data analysis, also known as “qualitative data analysis”, “qualitative research” or “qualitative research data analysis”, refers to the analysis of non-numerical data (or data) such as words, photos, and observations.

Offline data analysis

Offline data analysis is used for more complex and time-consuming data analysis and processing. It is generally built on cloud computing platforms, such as the open source HDFS file system and MapReduce computing framework. The Hadoop cluster consists of hundreds or even thousands of servers, storing several petabytes or even dozens of petabytes of data. Thousands of offline data analysis jobs are running every day, and each job handles hundreds of MB to hundreds of TB or more. The running time is minutes, hours, days or even longer.

Online data analysis

Online data analysis is also called online analysis and processing , which is used to process users’ online requests. It requires relatively high response time (usually no more than a few seconds). Compared with offline data analysis, online data analysis can process user requests in real time, allowing users to change the constraints and restrictions of analysis at any time. Compared with offline data analysis, the amount of data that can be processed by online data analysis is much smaller, but with the development of technology, current online analysis systems have been able to process tens of millions or even hundreds of millions of records in real time. The traditional online data analysis system is built on a data warehouse with a relational database as the core, while the online big data analysis system is built on the NoSQL system of the cloud-computing platform. If there is no online analysis and processing of big data, there will be no way to store and index a huge number of Internet webpages, there will not be today’s efficient search engines, nor will there be microblogs, blogs, and social networks based on big data processing. And so on.
