Week 4 LRA

Question 1

where would you check the -2 log likelihood of the ** constant only model**

Answer 1

see iteration history of block 0

Question 2

remove the non-significant predictors from the logistic model. where would you check?

LRA

Answer 2

Question 3

In which table can you find the regression equation?

Answer 3

See iteration history table van het gevraagde blok. Opschrijven op spiekbrief

Question 4

how would you interpet the Odds?

Answer 4

Zie Variables in the equation tabel > zie Exp (B)= Indien predictor X met 1 toeneemt neemt de kans op Y=1 ten opzichte van Y=0 met Exp(B) toe.

Question 5

how would you determine. Which combination of properties results in the highest Y

LRA

Answer 5

check which variables (properties) have positive regression weights and combine them.

Question 6

how would you determine the overall classification level?

LRA

kijk naar de tabel Classification Table en kijk naar het Overal Percentage onder Percentage Correct, dit is het percentage casussen die juist geclassificeerd wordt.

Question 7
