A Temporal Investigation of Crash Severity Factors in Worker-Involved Work Zone Crashes: Random Parameters and Machine Learning Approaches:
Reason:
In the context of work zone safety, worker presence and its impact on crash severity has been less explored. Moreover, there is a lack of research on contributing factors by time-of-day. To accomplish this, first a mixed logit model was used to determine statistically significant crash severity contributing factors and their effects. Significant factors in both models included work-zone-specific characteristics and crash-specific characteristics, where environmental characteristics were only significant in the daytime model. In addition, results from parameter transferability test provided evidence that daytime and nighttime crashes need to be modeled separately. Further, to explore the nonlinear relationship between crash severity levels and time-of-day, as well as compare the effects of variables to that of the logit model and assess prediction performance, a Support Vector Machines (SVM)
What is meant by machine learning approach?
Machine Learning is an AI technique that teaches computers to learn from experience. Machine learning algorithms use computational methods to “learn” information directly from data without relying on a predetermined equation as a model.

The answer would be Morrocco
A stimulus for which there is no conditioned response is called a unconditioned stimulus. The unconditioned stimulus is a<span> stimulus that naturally and automatically provokes and triggers a behavior or response.</span><span>During the process of classical conditioning, the neutral stimulus (NS) is converted into the unconditioned stimulus.</span>
Answer:
E) Matched pairs
Explanation:
The experiment is a matched pair design. A matched pair design is a type of design applied when there a only two treatment conditions, in this design, the subjects are grouped into pairs and are then matched to the treatment condition. For example, the subjects are matched to any of the two volume levels.
Answer:
D.) plant and animals species go extinct
Explanation:
Brazil and its rain forest habitat is seen as the lungs of the World, and steadily deforestation is killing our Earths lungs.
