I have created a model using e1071 package for Naive Bayes classifier. I need to print the conditional probabilities in below format.
P(C=c1)=0.32 P(A1=x1|c1)=0.33 P(A1=x2|c1)=0.67 P(A2=y1|c1)=0.25 P(A2=y2|c1)=0.75 P(A3=z1|c1)=0.26 P(A3=z2|c1)=0.49 P(A3=z3|c1)=0.25
When I type model name, I can see the conditional probabilities but don't know how to access individual value and use it to print result in above format.
I am new to R and not sure how to parse model and get data in this form. How to parse model and separate out data?
Just print $tables
> data(Titanic)
> m <- naiveBayes(Survived ~ ., data = Titanic)
> m$tables
$Class
Class
Survived 1st 2nd 3rd Crew
No 0.08187919 0.11208054 0.35436242 0.45167785
Yes 0.28551336 0.16596343 0.25035162 0.29817159
$Sex
Sex
Survived Male Female
No 0.91543624 0.08456376
Yes 0.51617440 0.48382560
$Age
Age
Survived Child Adult
No 0.03489933 0.96510067
Yes 0.08016878 0.91983122
And now you can read out for example P(Age=Child|Survived=No) = 3%
and P(Age=Child|Survived=yes) = 8%
, P(Class=Crew|Survived=No) = 45%
and so on.
