Hello,   I have a pipeline in SAS Studio, that starts with a data node, followed by a Clusering Node. My input data has around 15k rows; but I see that, when I run the clustering node, under the "Summary" tab, I see the "Segment Plot" shows around 9k records. My question is, what would be the reason there is this gap? A note here; when I investigate the output data, it shows the same number of records as the input data, so the only difference I notice is in the "Segment Plot" graph. I'd appreciate any comments here. Thank you!  ... View more

Hello,    I have a pipeline on Model Studio to create a segmentation model. Here is how it looks like:   I would like to do scoring in Model Manger, so I would need to register my model. However, under Pipeline Comparison tab in Model Studio, I see this notification:  "There are no pipelines to compare. In order to view Pipeline Comparison, successfully run a pipeline that contains a modeling node." Is there a way to register it through Model Studio interface or should I save the output and make the registration to Model Manager using SAS Code? I'd appreciate any suggestions! Thank you!  ...

Hello,   I have a couple of questions around using Model Studio for creating unsupervised models. I am currently using the "cluster object" in VA to make a segmentation, using k-means. I would like to move it to Model Studio. For the models such as a logistic regression, I have an option on my VA screen to click on "create pipeline" button to add my model to a current project in Model Studio. However, I think I cannot do that for cluster analysis in VA, would that be correct? So, I wanted to start a new project from scratch in Model Studio to replicate what I have done in VA, but there it is required to select a target variable, where I do not have one because it is a segmentation project, not a predictive model. So, I have chosen an ID variable as the target, just to be able to create a pipeline. So, my second question is, what would be the suggested target variable selection process for a k-means segmentation project, as I suspect my method is correct? Finally, I can add "clustering" node to the pipeline after the target variable selection but I am interested in adding several clustering nodes to the pipeline and making a comparison of its results. I Therefor, I'd like to use Model Comparison node but clustering node and model comparison nodes cannot be used together without adding a supervised learning node, I believe. So. my third question is, what should I do to create few different cluster nodes and compare their results?  Hope that makes sense! Thanks for the support.  ... View more

Hi all! Is it possible to apply regularization on models created in VA? Thanks! ... View more

Hello,  We can create models in VA using the visual interface with drag and drops, and as an alternative, we can create models in SAS Model Studio pipelines. I don't see what would be the pros/cons of these different interfaces. To me, only the interface is different. Could you please help me distinguish the capabilities/features of these two screens? Thank you!  ... View more

Hello,    I am creating a Logistic Regression Model in VA; I have results when I select certain set of independent variabes but using the same response variable, when I change the independent variables I have an error saying: "the analytic requires a categorical response variable with at least two levels". The response variable I selected is a binary variable with 2 categories and again the exact same response variable works on another logistic regression with different set of independet variables. What would be the reason for this error and how could I solve this? Thank you!  ... View more
