Linear no-threshold model — The linear no threshold model (LNT) is a method for predicting the long term, biological damage caused by ionizing radiation and is based on the assumption that the risk is directly proportional to the dose at all dose levels. In other words, the … Wikipedia
Threshold model — A threshold model in toxicology posits that anything above a certain dose of a toxin is dangerous, and anything below it safe. This model is usually applied to non carcinogenic health hazards.Edward J. Calabrese and Linda A. Baldwin wrote::The… … Wikipedia
Linear discriminant analysis — (LDA) and the related Fisher s linear discriminant are methods used in statistics, pattern recognition and machine learning to find a linear combination of features which characterize or separate two or more classes of objects or events. The… … Wikipedia
Linear least squares — is an important computational problem, that arises primarily in applications when it is desired to fit a linear mathematical model to measurements obtained from experiments. The goals of linear least squares are to extract predictions from the… … Wikipedia
Linear least squares/Proposed — Linear least squares is an important computational problem, that arises primarily in applications when it is desired to fit a linear mathematical model to observations obtained from experiments. Mathematically, it can be stated as the problem of… … Wikipedia
Linear least squares (mathematics) — This article is about the mathematics that underlie curve fitting using linear least squares. For statistical regression analysis using least squares, see linear regression. For linear regression on a single variable, see simple linear regression … Wikipedia
Linear classifier — In the field of machine learning, the goal of classification is to group items that have similar feature values, into groups. A linear classifier achieves this by making a classification decision based on the value of the linear combination of… … Wikipedia
Quasi-threshold graph — In graph theoretic mathematics, a quasi threshold graph is a graph that can be constructed using the following rules: # K 1 is a quasi threshold graph #If G is a quasi threshold graph, then so is the graph obtained by adding a new vertex… … Wikipedia
Critical threshold — Critical threshold, a notion derived from the percolation theory, refers to a threshold, that summons up to a critical mass. Under the threshold the phenomenon tends to abort, above the threshold, it tends to grow exponentially. In cases where… … Wikipedia
