What are the characteristics of k-NN algorithm? (2 correct answers)
A. It requires statistical models
B. Data-driven, not model-driven
C. Applicable under certain assumptions
D. Makes no assumptions about the data
Homework Answers
k-NN is non parametric and this indeed means that it does not make any assumptions about the data given. Or can also be mentioned that the main purpose of the algorithm is indeed to use a a model where it has different points which are actually separated into classes on the whole and this means it is data driven.
Therefore (b) and (d) age the answers for this question

A variable is exogenous if it is: (choose all correct answers) A- not necessary for a given model B- not impactful on a given model's results C- not explained (or determined) within the given model D- Fixed or pre-determined in a given model. E- not included in a given model I'm very confused about how the definition of exogenous is applicable to this question.

Santorino Company produces two models of a component, Model K-3 and Model P-4. The unit contribution margin for Model K-3 is $6; the unit contribution margin for Model P-4 is $14. Each model must spend time on a special machine. The firm owns two machines that together provide 4,000 hours of machine time per year. Model K-3 requires 15 minutes of machine time; Model P-4 requires 30 minutes of machine time. What is the amount of machine time for...

1. Of the four models of DNA synthesis outlined by Okazaki,
Model B (semidiscontinuous) turned out to be the correct one. What
would the 30 sec profile have looked like if Model A (continuous)
were correct? Below are four scenarios for model A compared to the
original data. Select the one that is most consistent with
continuous synthesis of both strands based on the pulse labeling
strategy of Okazaki et al.
