Critical study in mathematical approach of data processing in experimentalresearch on the phenomenon of organizational stress
Abstract :
his paper proposes fo"r re'ression methods of processin' e*perimenta% data to the
phenomenon of or'aniationa% stress. he fo"r re'ression methods are, the method of %inear
re'ression- po%ynomia% re'ression method- the e*ponentia% re'ression method and %o'arithmic
re'ression method. $ependin' on the processin' method e o/tain an inde* hose va%"e
can vary dependin' on the method. he method that 'ets the %oest n"m/er is the method
ith the hi'hest de'ree of re%ia/i%ity in researchin' the phenomenon of or'aniationa% stress.
$ataprocessin' methods are m"ch more n"mero"s diverse- /"t e stopped on these fo"r
herein. he data/ase "sed for the st"dy inc%"des staff- decision ma3ers- from ! #onea
(!ine #onea) and as co%%ected in the fie%d in 5"'"st 201.
Usin' mathematica% re'ression form"%as- e esta/%ish the %as of variation of the
phenomenon of stress ithin the or'aniation #onea !ine- 6"nedoara o"nty in omania
and the confidence in each %a of variation. $ependin' on the va%"e of this ratio res"%ted from
each method of re'ression- comparin' each other- e address in critica% manner hich of the
%as of variation ca"sed /y a partic"%ar method of re'ression is c%oser to the tr"th.

General concept of stress
e'ard%ess if e ant or not- e have to face ith stress thro"'ho"t o"r %ives. 8t is a common
phenomenon /"t sti%% e do not 3no ho to '"ard a'ainst stress and its effects. e

stressed. 5nd nothin' is ron', a%% of the a/ove are mas3s of stress.
5s etymo%o'y- stress as a concept comes from n'%ish and means ;constraint- s"fferin'; /"t
a%so has the sense of /"rden- stress- tension- /ein' ta3en from physics- as e*cessive constraint
