[@UmairSajid]

Hello Dr. Rai, thank you for a very informative video. One thing that I would like to add based on my limited knowledge: For a skewed class distribution such as in the data, it is more importance that the model is able to predict the abnormal cases then it is to predict normal cases. If we just look at the mis-classification error, then the model may be aligned towards the class with higher percentage of data. One way to avoid that is to reduce the disparity between the class types by over/under sampling techniques. Another way is to use the Area under the precision-recall curve as a measure of model evaluation. Your comments and feedback on this would be appreciated.

[@bkrai]

That's correct. For more details about class imbalance problem, refer to this link: kzbin.info/www/bejne/fqCVfJ-sr8-Ynck

[@christan7434]

Thank you Professor Rai for taking the time to show us the ropes. Regarding the mis-classification error table, may I know: what is the difference between that and the Confusion Matrix. I notice the calculation for "accuracy" is the same as the Confusion Matrix, simply "sum(diag(tab))/sum(tab)", but for Confusion Matrix, the Actual is on the vertical versus what you stated in video for Actuals in the horizontal. Thanks, and looking forward to more videos from you

[@bkrai]

Both confusion matrix or mis-classification table are same.

[@nayeemislam8123]

Sir, I have a few questions: 1. How do you find statistically significant variable after developing a decision tree model with all variables? Ho 2. Suppose all variables in a decision tree is coded as POOR, FAIR, GOOD, then how to find the probabilities of each (POOR, FAIR, GOOD) at non terminal nodes of the tree and also number of sample in each category? I need to show this in my plot. 3. What is the best approach in developing a decision tree model? Developing a model on the training data using K Fold Cross Validation OR Developing a model on training data and then going for cross-validation and pruning process using a function like cv.tree() which allows us to choose the tree with lowest cross validation error rate? Which method is better? 4. How to find out the value of the standardized importance of independent variables using CART in R?

[@bkrai]

1. P-values on the tree indicate statistical significance. 2. You can find it only at the terminal node. 3. k-fold CV is always better to avoid over-fitting. 4. Higher a variable on the tree, more important it is. For variable importance you can also try this link: kzbin.info/www/bejne/mnvGnYF_g5KHhtE

[@carlosfernandezgalvez3023]

Hi! thank you for all your videos. I'd just like make a little comment: ctree function implements 'Conditional Inference Tree', not 'Clasification Tree'. In fact, it can develop clasification trees, but the fundamentals are different. Thank you for all the work you are doing! very usefull. Carlos

[@takakosuzuki2514]

Hi Dr.Rai. I encountered an error on #Misclassification part. I got the table for using the library(party), but I got "all argument must have the same length" when using the rpart() one. But if I use validate set with the rpart package, the table can be generated.

[@bkrai]

Difficult to say much without looking a the code. But you can review your code again, there may be some typo.

[@harishnagpal21]

Nice video Bharatendra. One question.. you said that we need to optimize the model.... how to do that ie how to optimize our model! Thanks

[@bkrai]

You can make changes to settings in 'control' to see what helps to improve the model. In the example, I used only 3 variables just for illustration, but you must start with all variables for a better performance.

[@harishnagpal21]

thanks :)

[@rakeshvikhar]

I am a beginner.. could you help me understand if we can use linear/logistic regression todo the prediction here? I have referred your vehicle example and so got confused if we can use that model here.

[@bkrai]

Yes, you can use logistic regression as response variable is of factor type. For more see: kzbin.info/www/bejne/d4fbaIqZZqiEbbs

[@MatiToGuzior]

Greetings! I came back to this video after a while as it still seems to be the best one regarding Decision Trees out there. I have a quiestion regarding significance of variables. Do you have a video covering this subject? Any techniques I could apply while working on my Decision Tree? thank you

Thank you Dr Rai. I have a question about the tree pruning. Prior to the pruning some of the trees were able to classify patients as pathological but after pruning( by changing the control functions) none of the trees identify the pathological patients. If we were to specifically identify patients with suspected pathology how can we modify the control functions or the initial formula included in the "ctree()" function?

[@atiquerahman3766]

Hi Sir, Your videos are really helpful.It has really helped me a lot, I have few doubts though.I have just started learning data science so these doubts may be naive. 1) On what basis we decide that we should put this much data into training, validation, and testing respectively? 2)Is there any criteria(such as r-square in regression models, Chi-square for logistic regression) for decision trees so that we can say how good our model is?

[@bkrai]

1) one may experiment with different partitions such as 50:50, 60:40, 70:30, etc., and see what works best. There is no single partition ratio that will work well in all situations. 2) if your y variable is categorical, mis-classification error is used for model performance assessment.

How can we export the first tree prediction (View(predict(tree,validate,type="prob"))) into XL? When using a data frame they come out horizontally and unreadable.

[@raymondjiii]

That was awesome but I found that with my dataset I get a completely different decision tree using the rpart package. Without rpart, the tree is what I expected it to be and with rpart - in some ways it's almost opposite. I'm only comparing the two trees with my training data.

[@raymondjiii]

I think I know what the problem is - with rpart trees you only get a little "yes" and "no" marker on the root node. In my case "yes" goes to the left of the tree and "no" goes to the right of the tree. If I assume that direction is always the case then things are okay. I do wish that the "yes", "no" little while boxes were printed at every non leaf node so it's very clear which way the path is going. (I wonder if there's an option for that?) Thanks for the great video.

[@OrcaChess]

Hello! I gave my decision tree 97 different features but the decision tree only picked one of these features to make his decision. Is that normal that it doesn't consider all the features for its decision?

[@bkrai]

It runs with default setting. By making changes to default settings you may be able to make it include some more. But features that have very little impact on the response are unlikely to be included.

[@DhingraRajan]

It can happen when one of the feature is the close predictor for y. Then that value is quite enough to predict the y alone.

[@sudanmac4918]

Sir what is the difference between rpart() and ctree(). And when to use it??

I have a query and i tried to google it but I couldn't find any satisfactory answer against it. The question is what is the difference between ctree and rpart tree?

[@bkrai]

+Mahum Khan Cree is a function within package called "party" for decision tree. Similarly rpart is a function within a package with the same name "rpart". Both are use for decision tree. I prefer party as it is said to be more accurate. If you search "party vs rpart' you can see many good explanations.

[@vishnukowndinya]

hi sir can u pls explain about pruning of tree. on what basis we do prune ?

[@bkrai]

When you have decision trees that are too big, 'pruning' helps to reduce size of the tree by removing those parts that do not help much in correct prediction of the outcome. It helps to avoid over-fitting and improve prediction model accuracy.

[@javeda]

Hi, I wanted to ask which is most appropriate software for conducting SEM along with moderation analysis, in case of categorical, nominal (binary and multinomial) and ordinal variables as outcome/dependent/endogenous variables ?

[@kanhabira]

Thanks sir for this interesting video. I am facing a problem. My dependent variable is binary(0,1). When I run predict, the estimated values appear in in decimals despite remove "type". So, misspecification error is close to 1. Could you please suggest how I can get the predicted value as 0/1.

[@neera842006]

I am also getting same error message

[@dhavalpatel1843]

You should always pass the model as the first argumnet in predict function. The second parameter should be a data frame of predictor variables only. You can specify type=”prob” as an extra argument to get probabilities of every factor of y. Either type=”class” directly gives you the class of predicted values. By default type argument is set up differently for every R version.
