<div>An inequality is an [[equation]] where one side is not necessarily equal, or may not, to the other.<br />
<br />
These come in four kinds;<br />
<br />
# An equation which the left hand side is strictly greater than the right denoted <math>></math><br />
# An equation which the left hand side is greater than or equal that the right denoted <math>\geq</math><br />
# An equation which the left hand side is strictly less than the right denoted <math><</math><br />
# An equation which the left hand side is greater than or equal that the right denoted <math>\leq</math><br />
<br />
For example, 4 is greater than 3, so either;<br />
<br />
4>3<br />
<br />
3<4<br />
<br />
are true statements.<br />
<br />
The inequalities are wildly used in more advanced mathematics for example the [[cosine function]] is always between -1 and 1 inclusive so you can write;<br />
<br />
<math>-1\leq\cos x\leq1\; \forall x\in\mathbb{R}</math>.<br />
<br />
This gives the function [[bounds]].<br />

<div>An '''equation''' is a [[mathematical formula]] involving an equivalence sign (=). It is a statement asserting equality. Its opposite is <math>\neq</math>.<br />

<div>'''Regression''' is a method in statistics for fitting a curve through a set of points as closely as possible.<br />
<br />
The most common type of regression is [[linear regression]], which uses a straight line as the curve.<br />
<br />
Regression is done using a least squares estimator.<br />
