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.

Key words,

!athematica% re'ression- minin'- or'aniationa% stress- %a of variation- compared criticity

Introdoction :

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

e*perience an'er- panic- apathy- e are tired- fr"strated or fearf"%: rapid conc%"sion is, e are

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

(psycho%o'ica% and medica%) to hich man can face adversity.

Sco"r'e of 6"manity- e "sed to %oo3 at stress as somethin' p"re%y ne'ative- a%tho"'h he hasa positive component. Stress- as an e*pression- and a%so as rea%ity is so %itt%e "nderstood. he

a/sence of stress is death- it means the a/sence of any physica%%y and menta%%y response to
