In this first example, all the KmL's step are fully detailled.
Data are artificial data. They are generate by the function generateArtificialLongData(). There is three groups. The first is compoind of 60
individual whose trajectories are rising up. The second is a group of 50 individual whose trajectories are stable. The third is a group of 40
individual whose trajectories are going down.
In each group, the noise follows a normal law with mean one, standard deviation of three.
> dn1 <- generateArtificialLongData( + functionNoise=function(t){rnorm(1,0,1)}, + nbEachClusters=c(60,50,40) + ) |
Here are the artificial trajectories that have been generated:
> kml(dn1,3,1) |
According to Calinski criterion, the optimal number of cluster is three.
