It is a clustering algorithm that is a simple Unsupervised algorithm used to predict groups from an unlabeled dataset. let me show what type of examples we gonna solve today. There is some literature on multi-output regression (good summary here), but these involve scales of predicting high dimensional vectors(or even matrices), rather than just 3 numbers, so I don't know how useful this literature would be for your case, but that's where I would look if you're insistent on having a single model predict 3 outputs. Interestingly kalman means (predictions) are similar in Splunk and Python but confidence interval are way apart. Using this dataset, where multicollinearity is a problem, I would like to perform principal component analysis in Python. size is an optional numeric argument.
