### Factor Analysis
Consequently, the percentage of variance for this cluster (Functional risk) in Table 5 was calculated as 4.762 + 3.686 + 4.338 + 3.501 = 15.876%. \begin{table}

Table 5: Factor reduction for the risk factors: five new categories. In Table 5, the risk factors grouped in five clusters are highly manageable without losing a large amount of data, and therefore just 100% - 79.9% = 20.1% of the existing information was compromised.
