A curtailment rule would observe this fact, halt testing after the seventh item, and prescribe that the respondent be "screened in," thus eliminating the respondent burden that would have resulted from administering the final ten items.
Because this respondent cannot reach the cutoff value of 9 even if he/she receives a score of 4 on both the sixteenth item and seventeenth item a curtailment rule would halt testing after the fifteenth item and prescribe that the respondent be "screened out".
Regardless of the respondent's answer to the seventeenth and final item (which has a maximum possible score of 4), he/she cannot possibly reach the cutoff value of 9. A curtailment rule would observe this fact and halt testing after the sixteenth item, prescribing that the respondent be "screened out" (i.e., that the respondent receive a negative result from the COMM).
To summarize the above, a curtailment rule halts testing if (i) the respondent's cumulative score reaches the cutoff value (in which case the respondent is "screened in") or (ii) the respondent's cumulative score is low enough that he/she cannot possibly reach the cutoff value, regardless of his/her future answers (in which case the respondent is "screened out").
Energy curtailment regulation is increasingly applied in distribution networks.
First, we describe how the stopping rules of curtailment and stochastic curtailment can be applied to the COMM.
An example of such a table will be presented in a later section; the table giving the stopping rules of stochastic curtailment will be compared to the analogous look-up table for curtailment.
The stopping rules of stochastic curtailment may then be written in a simple look-up table that can be used for new respondents.
The results of the logistic regression analysis were then used to find the stopping rules of stochastic curtailment (i.e., to find the specific cumulative COMM scores that would result in early stopping at each stage of the test, and write them in look-up tables).
These results illustrate that SC-90 is the most liberal stopping rule of the four (it has the largest range of scores that result in early stopping), followed by SC-95, SC-99, and curtailment (the most conservative stopping rule).
