This article considers the relationship between two variables in two ways: (1) by using regression analysis and (2) by computing the correlation coefficient. By using the regression model‚ we can evaluate the magnitude of change in one variable due to a certain change in another variable. For example‚ an economist can estimate the amount of change in food expenditure due to a certain change in the income of a household by using the regression model. A sociologist may want to estimate the increase

pattern recognition In machine learning‚ pattern recognition is the assignment of a label to a given input value. An example of pattern recognition is classification‚ which attempts to assign each input value to one of a given set of classes (for example‚ determine whether a given email is "spam" or "non-spam"). However‚ pattern recognition is a more general problem that encompasses other types of output as well. Other examples are regression‚ which assigns a real-valued output to each input; sequence

Patterns of Evolution Humans alter our environment to suit our needs rather than adapt to our environment based on environmental stressors. Due to this fact‚ we are unlikely to be affected by the pressures of natural selection. We will not likely be affected by further evolution. In convergent evolution‚ unrelated species living in the similar environments become more and more alike in appearance as they adapt to the same kind of environment. Dolphins and sharks are examples of convergent

I want to know how CCE pattern is absorbed by schools‚ teachers‚ parents and students. On the surface‚ CCE looks lucrative with a scope to assess a child’s overall performance.
