What is the tail removal method?
Truncation method is a mathematical value-taking method. It is mainly used to remove the decimal part of a number and take its integer part to get an approximate value. This method is usually used in life, for example, when estimating or processing data, in order to get concise answers or eliminate outliers. The specific operation of truncated method is to convert the required truncated value into decimal, and then directly remove the decimal part and take the integer part. When using the truncation method, it is necessary to carefully select the deleted data points according to the specific situation, and pay attention to its possible impact. There are other commonly used methods to deal with outliers, such as replacement method, truncation method and so on. The replacement method is to replace the abnormal value with other numerical values, such as median or average; Truncation method is to limit the data in a certain range, for example, to limit the data in a certain standard deviation range, and it is necessary to choose a suitable method for data processing according to the specific situation.
