Linear Regression deals with the numerical measures to express the relationship between two variables. Relationships between variables can either be strong or weak or even direct or inverse. A few examples may be the amount McDonald’s spends on advertising per month and the amount of total sales in a month. Additionally the amount of study time one puts toward this statistics in comparison to the grades they receive may be analyzed using the regression method. The formal definition of Regression

1. An inverse or negative relationship is a mathematical relationship in which one variable, say y, decreases as another, say x, increases. For a linear (straight-line) relation, this can be expressed as y = a-bx, where -b is a constant value less than zero and a is a constant. For example, there is an inverse relationship between education and unemployment — that is, as education increases, the rate of unemployment decreases Inverse relationships and their counterpart, direct relationships, are

The order of a matrix having m rows and n columns is m x n. A matrix is an ordered set of numbers listed rectangular form. Example. Let A denote the matrix [2 5 7 8] [5 6 8 9] [3 9 0 1] This matrix A has three rows and four columns. We say it is a 3 x 4 matrix. We denote the element on the second row and fourth column with a2,4. Square matrixIf a matrix A has n rows and n columns then we say it's a square matrix. In a square matrix the elements ai,i
