This standard replaces GB/T 8056-1987 "judge and deal with processing and interpretation of statistical outliers in exponential sample data." The standard
Registration and GB/T 8056-1987 compared to, changes in technology content include.
--- Increasing the terms, definitions and symbols;
--- The "index sample outliers identifying and dealing" to "judgment and treatment indices sample outliers";
--- The term "outlier detection" and "high outliers" were changed to "straggling value" and "statistical outlier" and further defined the two
Meaning and each other's differences;
--- Increasing the level of detection level and removing the definition;
--- Detectable levels in the original standard "detection level is generally taken as 1%, 5% or 10%" with "unless an agreement in accordance with this standard
The parties have agreed otherwise, the detection level should be 0.05 ";
--- Clearly defined value culling level agreement Unless otherwise agreed by the parties in accordance with this standard, excluding the level should be 0.01;
--- Increasing the variety of situations "statistical outlier" test step;
--- The "no outliers" and "not highly unusual outliers" were changed to "No outliers" and "No statistical outliers

--- Increase bilateral outlier test, multiple outlier test, Censored Samples outlier test sample.

Introduction
Engaged in scientific research, industrial and agricultural manufacturing and management are inseparable from the data, and these data collation, analysis and interpretation are not from
Open statistical methods. Statistics is the study of digital data collation, analysis and correct interpretation of a subject. Each person takes from different sources
Have a variety of digital information, which digital materials are usually chaotic, we must organize and abbreviated to use, along with a comprehensive statistical
The method can make the data sorting, orderly arranged, graphical or a small amount of several important parameters, the number of feature data can express the
Come, both to avoid incorrect interpretation, but also will be satisfied with the data to minimize costs, improve economic efficiency.
"Data processing and interpretation of the statistics" contains a number of national standards, they are.
--- Statistical tolerance interval is determined (GB/T 3359)
--- Mean estimates and confidence intervals (GB/T 3360)
--- In comparing the two paired observations Mean (GB/T 3361)
--- Binomial distribution parameter estimation and testing (GB/T 4088)
--- Poisson distribution parameter estimation and testing (GB/T 4089)
--- Normality test (GB/T 4882)
--- Judge and deal with normal sample outliers (GB/T 4883)
--- Normal distribution with mean and variance estimation test (GB/T 4889)
--- Normal distribution mean and variance test efficacy (GB/T 4890)
--- Judge and deal type Ⅰ extreme value distribution of the sample outliers (GB/T 6380)
--- Gamma distribution (Pearson Ⅲ distribution) parameter estimation (GB/T 8055)
--- Exponential distribution sample outliers judgment and processing (GB/T 8056)
The standard is no corresponding international standards.
Statistical processing and interpretation of data
Analyzing exponential distribution and processing of sample outliers
1 Scope
This standard specifies the judge and deal with samples from an exponential distribution of outliers general principles and implementation steps.
This standard applies to samples from the overall index.

0, x0 ≤
Heng 0
Where β > 0.
3.1.2
One or more sample observations, they leave the other observations farther, suggesting that they may come from different population.
NOTE. Press outliers significant extent into straggling value and statistical outliers.
3.1.3
In culling levels (3.1.6) under the statistical test is significant outliers.
3.1.4
In the detection level (3.1.5) under the statistical test is significant, but excluding horizontal (3.1.6) without significant outliers.
3.1.5
Significance level for the detection of outliers and specified statistical tests.
Note. Unless otherwise agreed by the parties to reach an agreement in accordance with this standard, the detection level should be 0.05.
