[#491] constant variance is classified in assumptions testing as
Correct Answer
(B) homoscedasticity
Explanation
Solution: Constant variance is classified in assumptions testing as homoscedasticity. The assumption of homoscedasticity (meaning “same variance”) is central to linear regression models.
[#492] As compared to cumulative average-time learning model, learning model which predicts more cumulative total time to produce more units is known as
Correct Answer
(A) incremental unit time learning model
Explanation
Solution: As compared to cumulative average-time learning model, learning model which predicts more cumulative total time to produce more units is known as incremental unit time learning model.
[#493] Model, in which produced unit doubles every time as cumulative average time per unit decreases, by a constant percentage can be classified as
Correct Answer
(A) cumulative average time learning model
Explanation
Solution: Model, in which produced unit doubles every time as cumulative average time per unit decreases, by a constant percentage can be classified as cumulative average time learning model. The cumulative average time learning curve represents the fact that the time spent per unit declines by a constant percentage as the number of units produced.
[#494] In specification analysis, assumptions related to variance states that:
Correct Answer
(A) variance of residuals is constant
Explanation
Solution: In specification analysis, assumptions related to variance states that variance of residuals is constant.
[#495] GRN number refers to________.
Correct Answer
(A) goods received note number
Explanation
Solution: A goods receipt note (GRN) is created to record the delivery of items from your suppliers. A GRN is created against an issued purchase order. When a GRN is created for an item, any pending item quantity for an approved indent request will be automatically issued.
