Data Mining in SAS

After doing a stepwise feature selection I get the following results:

What I am trying to predict is if a person is a morning person or not.

The dataset is a survey that has the following question

Do you find it hard to get up ealy? 0 = disagree or 1 = Strongly Agree

My question is, How do I interpret the results?

For Puncuality the survey had the following options:

1 = I am often early.

2 = I am always on time.

3 = I am often running late.?

Is there a way to know that people that are morning people are more punctual? I really do not know how to interpret the results. Note: After doing the Logistic regression my model is faily accurate.

Explanation / Answer

As per your question , your response variable is morning or not .

You want a interpret the punctuality variable which is a categorical variable .

And catagorica are

1-i am early

2- i am always early

3 - i am oftrenearly

When you run the regression it will give the significance p-values for the point 1 , 2 and 3 .

If above there points are significant then there must be on category in base line .

Suppose we put( 1- i am often early ) in a base one category. Then result depend on it .

Suppose the punctuality estimate for (2- i am always on) is 0.4 then , we can conclude that , if effect of the punctuality(2-i am always on) on response variable is e^0.4 as a baseline category is (1-i am often early )

Suggestions- suppose you are hard to understand the logistic regression then simple you can use the dummy stepwise regression . You can easily interpret it .

Thanks in advance
