Through typical examples, this paper analyses the error types in programming system and studies how to use debugging and testing methods to improve the correctness rate of programs so as to demonstrate that it is not easy to analyze, program and debug a good programming system successfully.

Introducing the error types of VB,the debugging aids and the application of the debugging technology.

The topic and development of error analysis, together with the definition and inclination of error taxonomy, warrant a complementation to and an integration of current error classification of various sorts.

Geometrical interpretation to two types of errors in hypothesis verification;

This paper discuss the relationship between two types of errors in statistical hypothesis , and points out choosing the primary hypothesis and the significant level in the actual application .

In statistical hypothesis testing,the relationship of two types of errors and how to reduce the probability of them are discussed,and how to choose the appropriate testing method of one-sided statistical test is also offered.

These studies have investigated into various aspects such as the definition of error, collection of error samples, error classification, causes of errors, and also give a conclusion of error analysis tendency of empirical and corpus-based study.

Linguists have developed various ways of error classification from different points of view, and so were the ways of error correction.
