| 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 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) |
| malignant smallpox | Malignant smallpox, usually of the haemorrhagic form. Synonym: malignant smallpox. Variola miliaris, a form of varioloid in which the eruption consists of miliary vesicles without the formation of pustules. (05 Mar 2000) |
| West Indian smallpox | A mild form of smallpox caused by a less virulent strain of the virus. Synonym: Cuban itch, Kaffir pox, milkpox, pseudosmallpox, pseudovariola, variola minor, West Indian smallpox, whitepox. Origin: Pg. Alastrar, to scatter over (05 Mar 2000) |
| confluent smallpox | A severe form in which the lesions run into each other, forming large suppurating areas. (05 Mar 2000) |
| haemorrhagic smallpox | A severe and frequently fatal form of smallpox accompanied by extravasation of blood into the skin in the early stage, or into the pustules at a later stage, accompanied often by nosebleed and haemorrhage from other orifices of the body. Synonym: fulminating smallpox, variola haemorrhagica. (05 Mar 2000) |
| smallpox | <disease, virology> This acute viral disease once claimed a high mortality rate, but was officially announced as globally eradicated in 1979. This was due to who vaccination programs. Headache, vomiting and fever precede, the eruption of a widespread rash that is raised, vesicular and finally pustular. The eruption follows a set pattern of dissemination, commencing on the head and face. When the final stage is passed scars (pockmarks) are left to disfigure the skin. (27 Sep 1997) |
| smallpox vaccine | A live vaccinia virus vaccine of calf lymph or chick embryo origin, used for immunization against smallpox. It is now recommended only for laboratory workers exposed to smallpox virus. Certain countries continue to vaccinate those in the military service. Complications that result from smallpox vaccination include vaccinia, secondary bacterial infections, and encephalomyelitis. (12 Dec 1998) |
| smallpox virus | <virology> Virus responsible for smallpox. Said to have been completely eradicated. Large DNA virus (brick like, 250-390nm x 20-260nm) with complex outer and inner membranes (not derived from plasma membrane of host cell). (18 Nov 1997) |
| fulminating smallpox | A severe and frequently fatal form of smallpox accompanied by extravasation of blood into the skin in the early stage, or into the pustules at a later stage, accompanied often by nosebleed and haemorrhage from other orifices of the body. Synonym: fulminating smallpox, variola haemorrhagica. (05 Mar 2000) |
