Nonresponse rate
| Glossary of Statistical Terms |
The fraction of nonresponders in a survey: the number of nonresponders divided by the number of people invited to participate (the number sent questionnaires, the number of interview attempts, etc.) if the nonresponse rate is appreciable, the survey suffer from large nonresponse bias.

Nonresponse, английский
In surveys, it is rare that everyone who is ``invited`` to participate (everyone whose phone number is called, everyone who is mailed a questionnaire, everyone an interviewer tries to stop on the street…) in fact responds. the difference between the "invited" sample sought, and that obtained, is the nonresponse.
Nonresponse bias, английский
In a survey, those who respond may differ from those who do not, in ways that are related to the effect one is trying to measure. for example, a telephone survey of how many hours people work is likely to miss people who are working late, and are therefore not at home to answer the phone. when that happens, the survey may suffer from nonresponse bias. nonresponse bias makes the result of a survey differ systematically from the truth.

Rate base, английский
- The value of a regulated public utility and its operations as defined by its regulators and on which the company is allowed to earn a particular rate of return.
- Defined in law or by the regulator as the regulatory asset value on which the allowed rate of return can be earned. this may be calculated according to a variety of accounting methods: fair value, prudent investment, reproduction cost, or original cost. depending on the jurisdiction, the rate base can include working capital and construction work in progress. it can be adjusted to take into account accumulated depreciation.

Geometric distribution, английский
The geometric distribution describes the number of trials up to and including the first success, in independent trials with the same probability of success. the geometric distribution depends only on the single parameter p, the probability of success in each trial. for example, the number of times one must toss a fair coin until the first time the coin lands heads has a geometric distribution with parameter p = 50%. the geometric distribution assigns probability p×(1 − p)k−1to the event that it takes k trials to the first success. the expected value of the geometric distribution is 1/p, and its se is (1−p)½/p.
Expectation, expected value, английский
The expected value of a random variable is the long-term limiting average of its values in independent repeated experiments. the expected value of the random variable x is denoted ex or e(x). for a discrete random variable (one that has a countable number of possible values) the expected value is the weighted average of its possible values, where the weight assigned to each possible value is the chance that the random variable takes that value. one can think of the expected value of a random variable as the point at which its probability histogram would balance, if it were cut out of a uniform material. taking the expected value is a linear operation: if x and y are two random variables, the expected value of their sum is the sum of their expected values (e(x+y) = e(x) + e(y)), and the expected value of a constant a times a random variable x is the constant times the expected value of x (e(a×x ) = a× e(x)).
