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.

Answer: A. Random assignment
Explanation:
During a social work research, a group is created to test the reliability of the results. The people in this group are not given any treatment and if they are, they are given a different treatment. Depending on whether the group was randomly chosen or not, this group is called a comparison group or a control group. While a control group is randomly assigned, a comparison group is not.
The product life cycle model, sales are expected to peak in the market stage.
The product lifestyles cycle is the route of the lifestyles of a product. It starts whilst the product is in development and ends after the product has A company has to be good at both developing new products and managing them in the face of changing tastes, technologies, and competition
Products generally go through a life cycle with predictable sales and profits. Marketers use the product life cycle to follow this progression and identify strategies to influence it.
The product life cycle (PLC) starts with the product’s development and introduction, then moves toward withdrawal or eventual demise. This progression is shown in the graph, below. been eliminated from the market.
