ON STATISTICAL MODEL OF NUMBER OF INJURED BY ACCIDENTS AT WORK
Abstract
Statistical relationship between a number of injured by accidents at work and amount of money spent on arrangements for improvement of working conditions and labour safety, as well as average number of listed employees in construction in Novosibirsk Region and in the Russian Federation is defined. Correlation between a number of accidents and financing of labour safety arrangement is estimated on the basis of the found dependence. Regression analysis is carried out using the least square method, with the following autocorrelation and multicollinearity test. Several multiple regression equations are found as the result of study of data for Novosibirsk Region, selection of model that described the suggested parameters best is proved, forecast is made. Multiple linear regression equation for injury rate in the Russian Federation is found, its parameters are checked, projected value of number of injured is calculated. Relationship between the factors under study is defined and suggestion towards the following use of the research results is made.
