ImportanceIndice:Analyzing Data Through of Percentage of Importance Indice and
Its Derivations
The Percentage of Importance Indice (Percentage_I.I.) bases in magnitudes, frequencies, and distributions of
occurrence of an event (DEMOLIN-LEITE, 2021)

This index can detect the key loss sources (L.S) and solution
sources (S.S.), classifying them according to their importance
in terms of loss or income gain, on the productive system. The
Percentage_I.I. = [(ks1 x c1 x ds1)/SUM (ks1 x c1 x ds1) + (ks2
x c2 x ds2) + (ksn x cn x dsn)] x 100. key source (ks) is
obtained using simple regression analysis and magnitude
(abundance). Constancy (c) is SUM of occurrence of L.S. or S.S.
on the samples (absence = 0 or presence = 1), and distribution
source (ds) is obtained using chi-square test. This index has
derivations: i.e., i) Loss estimates and solutions
effectiveness and ii) Attention and non-attention levels
