Sorry about that, yes, it should be uniformVectorRDD. Thanks Sean! Burak On Mon, Feb 9, 2015 at 2:05 AM, Sean Owen wrote: > Yes the example given here should have used uniformVectorRDD. Then it's > correct. > > On Mon, Feb 9, 2015 at 9:56 AM, Luca Puggini wrote: > > Thanks a lot! > > Can I ask

Yes the example given here should have used uniformVectorRDD. Then it's correct. On Mon, Feb 9, 2015 at 9:56 AM, Luca Puggini wrote: > Thanks a lot! > Can I ask why this code generates a uniform distribution? > > If dist is N(0,1) data should be N(-1, 2). > > Let me know. > Thanks, > Luca > > 20

Thanks a lot! Can I ask why this code generates a uniform distribution? If dist is N(0,1) data should be N(-1, 2). Let me know. Thanks, Luca 2015-02-07 3:00 GMT+00:00 Burak Yavuz : > Hi, > > You can do the following: > ``` > import org.apache.spark.mllib.linalg.distributed.RowMatrix > import o

Hi, You can do the following: ``` import org.apache.spark.mllib.linalg.distributed.RowMatrix import org.apache.spark.mllib.random._ // sc is the spark context, numPartitions is the number of partitions you want the RDD to be in val dist: RDD[Vector] = RandomRDDs.normalVectorRDD(sc, n, k, numParti
