The sample size is 120 companies based on the Cochran formula. The required data from the software was extracted. Datasheet analysis was used to analyze the data. Chow model, Hausman and combined regression were used.

The model suggests that 87% of the variations of the dependent variable with the independent and controllable variables can be explained, and the Durbin-Watson statistics reject the assumption of self-correlation between the components of the model.
