Some Widely Used Statistical Models
A repetitive experimental process is envisaged in which there are only two possible types of outcome. These types may take many and varied forms—success and failure, yes and no, diseased and healthy, large and small, etc. The requirements for valid application of the model are (i) the outcome from one application of the process is not influenced by the results of other applications of the process; (ii) the probability of a type 1 outcome (or a type 2 outcome) is constant over the time period or region of the study; and (iii) an objective method of sample selection has been employed.
