Abstract
Estimation of the effi ciency of linear connection modeling of factorized working conditions (13 variables are represented in 4 orthogonal factors) with 4 responses on injury rate is shown using regression and canonical analysis. It is established that a multiple correlation coeffi cient R for the responses taken by itself (injury cause, site and type of accident, severity of injury) has an average value = 0.38 including statistically signifi cant factors and canonical connection of these arrays taken into account in a target experiment is characterized by the value R = 0.6156. This is comparable with a human factor infl uence on injury rate (R = 0.4639) being identifi ed in the course of parallel experiment with the array data of person injured in consequence of health and safety accidents. At that, factor arrays considered in a target experiment do not have statistically signifi cant canonical correlation R = 0.2314. Practically the same informational value of the investigated arrays F (working conditions) and T (injury rate) was revealed after the target experiment completing.
