The asymmetry coefficient, the asymmetry coefficient and the kurtosis, how to calculate the asymmetry coefficient, the calculation options for the coefficient

The coefficient of asymmetry is not an easy concept. However, this is the opinion of the newcomers. Upon closer examination, this term is easily assimilated. This is perhaps the most important concept in the whole theory of probability. It is the coefficient of asymmetry and kurtosis that facilitate the calculation and detection of random variables. These values are calculated by the formulas. In order to know what the coefficient of asymmetry, you need to know the following information: the magnitude of the central torque and the value of the standard deviation. In addition, it is necessary that X, which denotes the coefficient itself, is known to be less than infinity. Otherwise, all calculations are meaningless. By X we mean not a finite number. In order to find the ideal solution and find out what the coefficient of asymmetry is in one or another case, you will need to use several more formulas. It is desirable that the result you get is close to zero.

Why is it so important to calculate the asymmetry index? This is necessary to collect statistical data and forecast the results. In all areas of activity, statistics play an important role. The coefficient of asymmetry in the case of its composition helps in calculating the behavior of the building after construction, the possibility of its destruction, and therefore helps to take measures to prevent such situations. And this is not an isolated case in which this mathematical operation makes sense: this is how the connection of the pipe to the flange is calculated before welding, any relative construction shifts are calculated ... Agree, it is easier to calculate the asymmetry coefficient and to prevent a possible error than to build a building or weld a part, and Then redo it. It is not only more convenient, but also cheaper: for conversion, as a rule, huge money is spent.

In the conventional formulas, the asymmetry coefficient is denoted as As. As a rule, such random deviations are predicted and introduced, which are not in fact. This is done in order to check how the entire structural system as a whole behaves, if such a mistake, even a minimal one, occurs. It is believed that the error in any case takes place to be. Only it can either spoil everything, or remain insignificant and not break the structure. This error can also be predicted and the calculation of the coefficients of asymmetry and kurtosis helps.

There is also a mass of similar statistical methods that are also characterized by their usefulness, but only the asymmetry coefficient helps to trace a near future and probability, which other methods can not provide. Among them: ordinal statistics, rank statistics, etc.

By the way, in order to calculate this coefficient, you can collect either information that has already been grouped, or even scattered, uncombined figures.

These calculations are most often used in the natural sciences, as well as banking, constantly in any construction calculations, because their indicators are extremely accurate and believable. The use of these calculations protects against subsequent, possibly irreparable errors.

So take the trouble to find a good extras for your company, so as not to "burn out" in any case. He will be able to predict the situation with the affairs of your enterprise no worse than any extrasensory, and in many ways even better. After all, figures have an advantage over words: they are always accurate. By the way, you can figure out the formulas yourself, if you are at least a little familiar with higher mathematics. It is enough simply to open a good textbook on statistics and consider the paragraphs that tell about the asymmetry coefficient. Good luck!
