Example 1.5 :Aircraft FastenersStudy of compressive strength of aircraft fasteners (Montgomery & Peck 1982).

Failure rate of fasteners over various pressure loads (2400 to 4300 psi).

Sigmoid curve is expected to model the failure rate of the fastener: None of the component is likely to fail at low pressure and vice versa.

Example 1.6 :Anti-pneumonia SerumSmith (1932) gave an example of bioassay, the classical case of binary data.

He studied the protective effect of serum no. 32 to the pneumococcus, bacteria related to pneumonia.

Two hundreds mice infected by the bacteria and then injected with different dose of serum 32.

Example 1.7 :Erythrocyte Sediment RateA study aimed to examine the relation between ESR and the plasma proteins: fibrinogen and gamma-globulin.

Thresholding was applied to create binary data since absolute value of ESR is unimportant.People with ESR < 20 mm/h are healthy.People with ESR > 20 mm/h are unhealthy.

Does the probability of ESR > 20 mm/h depend on the concentration of both proteins?

Example 1.8 :Women's Role in SocietySurvey by University of Chicago concerned with the relationship between education and sex of the respondents to attitudes towards the role of women in society.

Whether they agree or disagree with the statement: Women should take care of running their homes and leave running country up to men.
