To calculate street distances, you will need a graph that describes the length and connections of the streets. If you have that, you can use shortest path algoritms to find the distance between 2 points or between set of points. Shortest path algoritms are available in SAS/OR and SAS/SNA. ... View more

I guess you want to compare a linear SVM to your Logistic Regression. (Otherwise it's not fair ) Basically there is only one parameter, that you can use for tuning the linear SVM, it is the penalty value (C). SVMs do not outperform Logistic Regression in every situation. They are stable, work very well with high dimensional data... SVMs are maximal margin classifiers. They work the best if there is a margin. In business terms this means your event and non-event cases are very different. There are only a few "in the middle". Logistic Regression assumes a smooth transition of the probability as features change. Don't forget to compare your models on an independent test set. ... View more

obs= and firstobs= dataset options are designed to subset the data before it reaches the data step or a procedure. As they are data set options, they work almost in any circumstances. For example in a proc step. Obviously you don't have data step variables in a proc step.  obs= and  firstobs= can subset the observations very efficiently. point= works only in a data step, it is an option of the set statement. It is designed to allow random/direct access to specific observations. For example if you want to read the 10th, 20th and than again the 10th observation. ... View more

You should create a new variable with the Transform Node. The formula for the new variable should be simply:  _NODE_. Click on Formulas, than Create (upper-left corner) If you want to see the _NODE_ variable in the formula editor, change Leaf Role (in Decision Tree) to Input. ... View more

You can rename copy the _NODE_ variable with a Code Node or with Transform Node. Then you can connect a new Tree Node, the original _NODE_ variable won't  be overwritten. ... View more

1. You can change the names of the output datasets in nodes that produce them (Query Builder, Filter and Sort, Append ... Code Node). Sometimes you need to click on Modify sometimes it is enough to select Properties - Results. Then you must (re)run those nodes. This will create the new data sets. You don't need to recreate the whole diagram, but yes, it is a manual process. 2. Then you can change the inputs of nodes (tasks), that consume the work tables: Right Mouse Click - Select Input Data or in some cases(Append, Query Builder😞 Modify - and change datasources in the Task Instead of step 2. you can select Tools - Project Maintenance You can rename tables here. I found, that here you can choose only an existing table as a new the data source, but that new table should not exist in the project! For some tasks (Filter and Sort) I was unable to change the data source Message was edited by: Gergely Bathó ... View more
