| Abstract: | An estimation method of contamination rate based on entropy was proposed. It is useful for gross error statistic to avoid limited error selection. Two models of data main distribution were suggested to investigate contamination rate and the estimation methods of contamination rate based on entropy were given out. A numerical simulation was performed to analyze the influence of entropy truncation error on data contamination rate estimation. It is less influence for entropy truncation error to contamination rate estimation based on entropy. When truncation error is 0.01, the variation of contamination rate estimate is only 1%. The examples show that the estimation method of contamination rate based on entropy is reliable and superior to the traditional estimation. |
