T test: –
In simple terms, T test is a statistical test that is used to compare the means of two groups.
The t-test is not applicable in our Project 1, as it involves three variables, and our project is designed for comparisons between two variables
What is WLS?
With WLS, points of data have varied values with the objective to maximize the model fitting process by giving greater weight to reliable observations. Applying WLS improves the model of regression by including the weighted significance of each data item into consideration. In order to improve accuracy, the WLS output adjusts the model through taking into account the effects of each data point through set weights.
During the upcoming class, I plan to engage with the professor and TA to seek advice, how to implement WLS in the project.
