| mixed discrete-continuous random variable | <statistics> A random variable that may assume some values with probabilities and others with probability densities. For example, in a 35-year-old man with familial polyposis of the colon, the distribution of time until malignant disease occurs consists of a probability that he already has cancer (which would be assigned the waiting time 0), a probability density of developing it in the future and a probability that he will die of some other cause before he develops cancer.

| discrete | 1. Separate; distinct; disjunct. 2. Disjunctive; containing a disjunctive or discretive clause; as, "I resign my life, but not my honor," is a discrete proposition. 3. <botany> Separate; not coalescent; said of things usually coalescent. Discrete movement. See Concrete movement of the voice, under Concrete, Discrete proportion, proportion where the ratio of the means is different from that of either couplet; as, 3:6::8:16, 3 bearing the same proportion to 6 as 8 does to 16. But 3 is not to 6 as 6 to 8. It is thus opposed to continued or continual proportion; as, 3:6::12:24. Discrete quantity, that which must be divided into units, as number, and is opposed to continued quantity, as duration, or extension. Origin: L. Discretus, p. P. Of discernere. See Discreet.

| discrete character | Classifiable character that is also countable (e.g., number of progeny, number of teeth). Synonym: discrete character. (05 Mar 2000) |
| discrete random variable | A random variable that may assume a countable number of values, each with a probability strictly greater than zero. (05 Mar 2000) |
| discrete smallpox | The usual form in which the lesions are separate and distinct from each other. (05 Mar 2000) |
| discrete time model | <epidemiology> A model in which the system jumps from one state to the next at fixed intervals or timesteps. These difference models are simple to understand but often difficult to analyse; Contrast continuous time models. The parameters in such a model refer to the amount of change over the finite timestep; they are sometimes referred to as finite rates. In a (rather precise) sense, a differential equation is what you eventually get from a difference equation when you let the timestep get smaller and smaller and smaller. (05 Dec 1998) |
| discrete variable | A variable that may assume only a countable (usually finite) number of values. (05 Mar 2000) |
| age distribution | The frequency of different ages or age groups in a given population. The distribution may refer to either how many or what proportion of the group. The population is usually patients with a specific disease but the concept is not restricted to humans and is not restricted to medicine. (12 Dec 1998) |
| Bernoulli distribution | <statistics> The probability distribution associated with two mutually exclusive and exhaustive outcomes, e.g., death or survival. (14 Aug 2000) |
| binomial distribution | The probability distribution associated with two mutually exclusive outcomes; used to model cumulative incidence rates and prevalence rates. The bernoulli distribution is a special case of binomial distribution. (12 Dec 1998) |
| gaussian distribution | Continuous frequency distribution of infinite range. Its properties are as follows: 1) continuous, symmetrical distribution with both tails extending to infinity; 2) arithmetic mean, mode, and median identical; and 3) shape completely determined by the mean and standard deviation. (12 Dec 1998) |
| chi-square distribution | A distribution in which a variable is distributed like the sum of the the squares of any given independent random variable, each of which has a normal distribution with mean of zero and variance of one. The chi-square test is a statistical test based on comparison of a test statistic to a chi-square distribution. The oldest of these tests are used to detect whether two or more population distributions differ from one another. (12 Dec 1998) |
| multinomial distribution | Probability distribution associated with the classification of each of a sample of individuals into one of several mutually exclusive and exhaustive categories. (05 Mar 2000) |
| contagious distribution | <epidemiology> Same as an aggregated distribution. (05 Dec 1998) |
| poisson distribution | <epidemiology> The distribution which arises when parasites are distributed at random amongst hosts. (05 Dec 1998) |
