Marine Midland researchers were using individual interviews to collect these data.
<h3><u>
Explanation:</u></h3>
An information-gathering interview is a focused discussion with a specific determination that practices a question-and-answer format. Intentions are valuable erudition that can be gathered from interviews. Interview questions are regularly open-ended subjects so that in-depth knowledge will be obtained.
In the personal interview, the interviewer acts instantly with the respondent. They also grow a viable choice where there are short respondents. There are possibilities for reviewing to get underlying factors. The interviewer can seek in-depth information around the topic.
Answer:
d. It is best measured using the statistic variance inflation factor (VIF).
Explanation:
Multicollinearity is an important issue in multiple regression model, having many independent/ explanatory variables. Multicollinearity is the situation in which two or more independent variables are highly correlated. It is problematic because it increases the standard error of independent variable coefficient & undermines its statistical significance
Variance Inflation Factor [VIF] is a check & corrective measure of multicollinearity.
- VIF as a multicollinearity check : It quantifies the correlation between one explanatory variable with other explanatory variables.VIF = 1 implies there is no multicollinearity (correlation between independent variables); VIF upto 5 implies there is moderate multicollinearity (correlation between independent variables). VIF > 5 implies high multicollinearity (correlation between independent variables)
- VIF as a multicollinearity correction : Calculating
= σ^2 / ![[TSS j (1 - R^2j)]](https://tex.z-dn.net/?f=%5BTSS%20j%20%281%20-%20R%5E2j%29%5D)
; where TSS = total sum of square of variable j , σ^2 = j variance, R^2 j = R^2 from regressing all other independent variable on variable j
