| Poisson-Pearson formula | A formula to determine the statistical error in calculating the endemic index of malaria: let N = total number of children under 15 years in a locality; n = total number examined for the spleen-rate; x = number found with enlarged spleen; (x/n)100 = spleen-rate; e% = percentage of error; the percentage error will be, by this formula: (05 Mar 2000) |

| Poisson, Simeon Denis | <person> French mathematician, 1781-1840. See: Poisson distribution, Poisson-Pearson formula. (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) |
| countercurrent distribution | A method of separation of two or more substances by repeated distribution between two immiscible liquid phases that move past each other in opposite directions. It is a form of liquid-liquid chromatography. (12 Dec 1998) |
| hospital distribution systems | Systems for delivering hospital supplies, food, laundry, etc., to patient care areas. (12 Dec 1998) |
| sex distribution | The number of males and females in a given population. The distribution may refer to how many men or women or what proportion of either in 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) |
| skew distribution | An asymmetrical frequency distribution; in biology and medicine it is usually a lognormal distribution. (05 Mar 2000) |
| negative binomial distribution | <epidemiology> A distribution which is parameterised by a mean m and an aggregation parameter k which is large when aggregation is small; in fact as k becomes large, the negative binomial distribution approximates the Poisson distribution. (05 Dec 1998) |
| nitrogen distribution | Determination of the distribution of nitrogen in the urine among the various constituents. Synonym: nitrogen distribution. (05 Mar 2000) |

| Poisson distribution |
A one-parameter, discrete frequency distribution giving the probability that n points (or events) will be (or occur) in an interval (or time) x, provided that these points are individually independent and that the number occurring in a subinterval does not influence the number occurring in any other nonoverlapping subinterval. It has the form P(n, x) = e - x ( x) n /n!. The mean and variance are both x, and is the average density (or rate) with which the events occur. ...

| Poisson distribution |
A poisson distribution is a distribution of random occurrences in which one occurrence has no influence on any other occurrence. The variance of a poisson distribution is equal to its mean and therefore the standard deviation is equal to the square root of the mean of the distribution. Radioactive decay measurements follow a poisson distribution and therefore have a lower measurement error when more counts are accumulated.
