Embodiment 1
[0171] Embodiment 1, small sample test data estimation calculation example;
[0172] The small-sample data estimation method based on gray bootstrap and unascertained rational numbers is an analysis method that combines gray bootstrap method and unascertained rational number processing method to perform point estimation and interval estimation on small-sample data. Its principle is as follows: figure 1 shown.
[0173] In order to verify the effectiveness of the algorithm, the parameters are estimated for the interference power test data X={93.5,92.6,93.7,92.5,93.1,93.5} in a certain type of equipment test.
[0174] Using the gray bootstrap method to obtain a new test index measurement data set is {93.5, 92.6, 93.7, 92.5, 93.1, 93.5, 93.1, 92.7, 93.2, 93.6, 92.8, 94.0, 93.0, 92.5, 93.4, 93.0, 92.7, 92.2, 92.9,92.1,93.1,93.4,93.0,92.5,93.4,92.8,92.1,92.9,92.6,94.0}, a total of 30 data, the maximum value is 94.0, the minimum value is 92.1.
