Matrix

A graphical framework to receive a two dimensional data array (the scatter plot), which is principally used to establish correlation as part of a multi-variate analysis. 

The points on the matrix can be cross-referenced to the x-axis (horizontal) and y-axis (vertical) of the matrix.

The points in the matrix are either entire facilities or individual assets within facilities.


Purpose of the Matrix 
The primary purpose of a matrix is summarized below:

  • To draw correlations between data sets.
  • To identify patterns (trends, etc) in the data.
  • To classify/organize data into groups for analytical and classification purposes.
  • To benchmark individual assets or buildings against Key Performance Indicators (KPIs) and other measures and thresholds. 
  • To prioritize and make resource allocation decisions.
The matrix serves as a decision-support tool.



Elements of the Matrix
A matrix is comprised of the following components:
  • The horizontal axis ("x)
  • The vertical axis ("y")
  • The numerical scales along each axis (ie., indexes)
  • The quadrants (usually four)
  • The points (the scatter plot)
  • The resultant pattern (the copula)
  • The regression/trends applied to the pattern.

Types of Matrices
Within the field of asset management, matrices provide frameworks for certain types of useful analytics, including:

       Group 1

        Group 2
    For example, the condition of a building represented on the horizontal axis and the age of buildings represented on the vertical axis.



    Analysis of the Matrix 
    Listed below are the five patterns that may potentially be discerned in the scatter plot data:
    Listed below are some of the concepts to be used in analysis of a matrix:
