Regression Model A regression model is one of the most common machine learning models used for forecasting. The main idea of the regression model in air pollution prediction is that the model learns about the relationship between a dependent variable and a number of independent variables. There are different forms of the regression model, namely: linear regression and multiple regression. Linear regression is the simplest type of regression model as it only uses one independent variable as the model’s predictor....

Game Theory attempts to define these situations in mathematical terms and determine what would happen if every player acts rationally. Maybe an equilibrium can be reached which is why we all drive on the same side of the road within a country. Maybe this equilibrium will be worse for all players or maybe everyone will try to be as unpredictable as possible in their actions. In some way Game Theory, it's a way to mathematically model complex human behavior, to...

There is not much known about Euclid, the “Father of Geometry.'' We only know as much as he lived around 300 bc, and he taught in Alexandria, Egypt during the reign of Ptolemy I. Although the world still has his works and achievements throughout his books that still remain. He devised multiple theorems that laid the groundwork for geometry, subtlety linking his nickname “The Father Of Geometry” . He even developed a similar way of Geometry that we use today...

Game theory is a mathematical technique used to interpret the behaviour of interdependent decision makers who use strategic behaviour. It assumes that players are rational and that payoff matrices are predetermined and known to everyone. Most of these assumptions do not hold true in real life. Managers may be motivated by other factors when making strategic decisions like growth and revenue maximization or their corporate social responsibility. Additionally, it is hard to achieve complete information in real life which is...

Theorems and proofs both play a crucial role in mathematics as they serve as something more than the justification behind a result. Theorems are statements that can be demonstrated to be true by accepted mathematical operations and arguments. A theorem makes up some general principle, meaning it is part of a larger theory. The process of showing a theorem to be true is called a proof. The two simply tie together as they are both what geometry revolves around. With...

It was first in April 1998 that the Home Office introduced a methodical recorded system when it came to counting and recording crime statistics . Beforehand the statistic results gathered would not have been part of official figures and therefore would have been lost in translation and not reliable to be used as a data source for what crime was occurring across society. Throughout the years, the Department of Justice (DoJ) has been releasing these statistic reports bi-annually (Spring and...

A large number of methods for modelling are in vogue and evaluating the relative performance of different methods remains a continuous challenge in ecology and conservation biology. In general, the various methods used in species distribution modelling can be classified in two categories, one set of methods require species presence and absence data for model construction and other set of methods rely on presence only data for making predictions. Presence-only data differ from presence–absence data in that they indicate locations...

Geometry is a branch of mathematics that studies the shape, sizes, position of angles and dimension of individual objects and spatial relationships among various objects, and the properties of surrounding space. It is one of the oldest branches of mathematics. The work geometry originates from Greek, geo means earth and metron means measure. Eventually it was realized that geometry need not be limited to the study of flat surfaces (plane geometry) and rigid three-dimensional objects (solid geometry) but that even...

Introduction Social structures or networks such as access to education, employment, inclusion in society and so on are important prerequisites in shaping the health of people in any given circumstances. The extent to which we incorporate these factors coupled with biological agents explains why disease are produced (Berkman, Kawachi, & Glymour, 2014). For example people with good education have access to better quality health care and are well integrated in societies thus are rarely affected with mental health problems. This...
