Empowering Computer and Statistics
The statistical approach to random numbers is very particular. In gambling and games of chance, random numbers have the main role. So, in a sequence of posts in Armancomputer magazine, I will discuss probability distribution and introduce some commands in R language, to generate random numbers from the main statistical distributions such as Normal, Uniform, […]
Random numbers in computer data simulation and statistical distributions play an important role. Although we know that the numbers generated by computer algorithms are pseudo-random (No real Random), but in most cases we use these techniques to create random numbers in the range [a,b] (from a to b). In this article of Arman Computer magazine, we […]
In this article, with the help of examples, the use of the switch function in R language reviewed in armancomputer scientific magazine which has an important role to program multiple conditions. As you know, R is a computational programming specially design for statistics. The switch function in R evaluates an expression against the elements of […]
As in the calculation formula Average said, the role of each observation and value in calculating the average is equal and the same. If it is necessary that some observations have more or less importance in calculating the mean, weight (importance level) can be considered for them. In this article from Arman Computer Magazine, we […]
In statistics, classification is a technique that assigns an observation (or observations) to a set of categories (subpopulations). For example, you can assign a specific email to the class “spam” or “non-spam”. Obviously, this diagnosis is based on previously observed features (examples). In this text, we want to deal with classification with a statistical approach. […]
Day by day, we are aware of the impact of data science and the use of data mining techniques in the analysis of our sensory perceptions in our daily life. In the article we paid about the difference between data reporting and data analysis. In this regard, a semi-real story (maybe even real) was formed […]
Averaging and calculating the average is one of the data summarization indices. The average of mean is often used as a substitute for values so that a data set can be summarized into a single number. In this article from Arman Computer Magazine, we want to discuss a special type of average value called the […]
The word mean is used a lot in today’s life. Although these words are from specialized keywords mathematics and Arman Computer Magazine, we discuss the concept of average and its applications. The arithmetic mean, average, or average all refer to a type of statistical calculation that is included in the group of central statistical indicators […]
Critical thinking and problem-solving skills are essential for success in today’s world. They are the foundation of effective decision making, problem solving, and the ability to navigate complex situations. Without these skills, students will struggle to succeed in the classroom and in their future careers. Education is the key to developing these skills, and it […]
Perhaps you have heard the term machine learning and data mining and are curious to learn more about them. Although these two new branches of science have their roots in statistics, mathematics and computer science, but with significant growth, they are changing society and recognizing the laws of society. In this article from Arman Computer […]
