asymmetry measures

asymmetry measures

1. Asymmetry measures are indicators that allow establish the degree of symmetry (or asymmetry) that a probability distribution of a random variable without have to do its graphic representation.

2. In probability theory and statistics, the most accurate measure of asymmetry used part of the use of the standard third moment. The reason for this is that we are interested in keeping the sign of the deviations with with respect to the mean, to obtain if those that occur at the right of the mean than those to the left.

3. It can only be used in uniform distributions, unimodal and moderately asymmetric. It is based on the fact that symmetric distributions the mean of the distribution is equal to Fashion.

4. Asymmetry is useful in many fields. Many simplistic models assume a normal distribution, that is, symmetric about the mean. The normal distribution has zero skewness.
