simulation-validation

Which statement(s) is(are) most accurate about validation?

• To verify if the logic of the model is as intended
• To verify if the model reflects the real system
• To assure building the model correctly
• To assure building a correct model

Which validtation technique(s) is (are) subjective?

• face validity

• I-O transformation

• Turing test

Which is(are) TRUE about I-O transformation?

• need person's knowledge of the system
• invovled hypothesis testing
• treat the system/model as a blackbox
• The highest cost-to-value validation technique

Which test is most approriate when using historical input data in the I-O transformation?

• T-test
• pair-T test
• Either t-test or pair-T test

"The probability of detecting a incorrect model" is refered to ..

• alpha
• beta
• power of the test

Which one is (are) TRUE about type II error?

• similar to "false negative"

Given a difference, ℇ, between E(Y) and μ, the smaller n (replication), the .....

• higher probability of accepting Ho

• larger the power of the test

• the larger type I error

• the larger type II error

Suppose the C.I. of the model output average does not contain true value μ0 of the real system

• If the best-case error is > ε, more replications are required

• If the best-case error is > ε, the model needs to be refined

Suppose the C.I. of the model output average contains true value μ0 of the real system

• If the best-case error is > ε, more replications are required

• If the best-case error is > ε, the model needs to be refined

Suppose the C.I. of the model output average contains true value μ0 of the real system

• If worst-case error is > ε, additional replications are necessary

• If worst-case error is > ε, the model needs to be refined
