Linear regression
| Эпидемиологический словарь (глоссарий) |
- Линейная регрессия
- A special type of linear model where the output (dependent) variable is a simple weighted sum of the input (independent) variables. when the weights are functionally independent, the model is then linear in the parameters. classical linear regression also requires assumptions on a common error term across the domain of the predictors, as well as assumptions of independence and normality of the errors. (see figure l.2.) see also: data mining.
- Линейная регрессия. метод описания зависимости между двумя и более переменными путем расчета прямой или графа наилучшего соответствия [20].

- A proportional relation between two quantities, e.g., in 46 the equation y=cx, c is the constant y/x and states that y is a linear function of x. the term comes from the straight line with which such a function can be visualized within x-y coordinates. the notion of linearity is generalized to relations between many quantities, expressed in the form of linear equations, to a concept of time that progresses from an indefinite past to an indefinite future without parallel paths or loops, and to a causal network or lattice which proceeds directionally from antecedents to consequences without feedback.
Linear (adj), английский
- In mathematics and electronics, having a direct and proportional relationship among characteristics or variables. for example, the output of a linear amplifier is directly proportional to the input.
- Proceeding sequentially. for example, a linear search is one that moves from a to b to c.

Linear association, английский
Two variables are linearly associated if a change in one is associated with a proportional change in the other, with the same constant of proportionality throughout the range of measurement. the correlation coefficient measures the degree of linear association on a scale of −1 to 1.

Regression, английский
- Statistical technique used to evaluate relationships among variables (22).
- Регрессия

- Regression commonly refers to the process of developing an empirical (data-driven) model to predict and/or explain one or more attributes in a database or set of data. it is most frequently associated with the simple linear model (y=mx+b) taught in most introductory statistics courses; the same ideas have been extended in many directions, including classification problems. when the emphasis is on hypothesis testing and simple models, the regression output is typically a few parameters that provide a direct linkage from the input variables to the predicted variables (or classification). in other situations the emphasis is on explaining as much of the variability in the output variables as is "reasonable" from the input variables. in this case, there are a number of "advanced" techniques, such as smoothing splines, decision trees, neural nets, and so forth, for which there are many "free" parameters. the meaning of any one of these parameters can be obscure. many data mining techniques are, at their core, variations on well-known regression techniques. see also: classification, clustering, decision trees, neural nets.
- The reappearance of a previously fixed problem.
- The statistical process of predicting one or more continuous variables, such as profit or loss, based on other attributes in the dataset.
- A mathematical technique used to explain and/or predict. the general form is y = a + bx + u, where y is the variable that we are trying to predict; x is the variable that we are using to predict y, a is the intercept; b is the slope, and u is the regression residual. the a and b are chosen in a way to minimize the squared sum of the residuals. the ability to fit or explain is measured by the r-square.
- A seaward retreat of a shoreline, generally expressed as a seaward
Independence, английский

- Self-suficiency concerning information. independent systems are closed to information. variation outside the boundaries of independent systems do not affect the variation within. there is no input. in statistics, two variables are independent if the coocurance of their values is mere chance, e.g., zero correlation. in logic and set theory, two variables are independent if the relation between them is the mere cartesian product of two properties. two individuals are independent if each does what he wants to do, neither having to consider the behavior of the other. a clock is designed to be independent of variation in temperature, geographical location including gravity while it is correlated with other clocks and communicating its output states to an observer. independent systems maybe a source but not the receiver of communication (->closed system, ->closure). .
