| 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 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) |
| acquired character | A character developed in a plant or animal as a result of environmental influences during the individual's life. (05 Mar 2000) |
| recessive character | An inherited character determined by an allele in homozygous state only. See: dominance of traits. (05 Mar 2000) |
| mendelian character | An inherited character under the control of a single locus (although perhaps modified by genes at other loci). (05 Mar 2000) |
| character | In current usage, approximately equivalent to personality. The sum of the relatively fixed personality traits and habitual modes of response of an individual. (12 Dec 1998) |
| character analysis | Analysis of the defenses and personality traits that characterise an individual. (05 Mar 2000) |
| character armor | A habitual pattern of organised defenses against anxiety. (05 Mar 2000) |
| character disorder | A term referring to a group of behavioural disorder's, now replaced by a more general term, personality disorder, of which character disorder's are now a subclass. (05 Mar 2000) |
| character neurosis | A subclass of personality disorders. (05 Mar 2000) |
| classifiable character | A character that allows individuals to be sorted into distinct but not quantitative classes, e.g., blood types. (05 Mar 2000) |
