Problems with linear model in Incanter 1.9.2

[Goldritter]

Hello,

I try to use the linear model in Incanter 1.9.2 but I get always the error, that "something" cannot be cast into a Number.

Here the example codes I try to use (one is an example from https://github.com/hamishdickson/clojure-machine-learning/blob/master/src/clojure_machine_learning/linear-regression/linear-regression.clj) :

(def X (cl/matrix [8.401 14.475 13.396 12.127 5.044

                   8.339 15.692 17.108 9.253 12.029]))

(def Y (cl/vector [-1.57 2.32 0.424 0.814 -2.3 0.01

                   1.954 2.296 -0.635 0.328]))

=> #'export.esicm.export/X

=> #'export.esicm.export/Y

(INCANTER-STATS/linear-model Y X)

ClassCastException clatrix.core.Vector cannot be cast to java.lang.Number  clojure.lang.Numbers.minus (Numbers.java:137)

(INCANTER-STATS/linear-model [1 2 3] [1 2 3])

ClassCastException mikera.vectorz.Scalar cannot be cast to java.lang.Number  clojure.lang.Numbers.minus (Numbers.java:137)

I use Clojure 1.8.0 and have following dependencies:

;; Math dependencies
[org.clojure/math.numeric-tower "0.0.4"]
[org.clojure/data.priority-map "0.0.5"]
[org.clojure/math.combinatorics "0.1.4"]
[net.mikera/core.matrix "0.60.3"]
[clatrix "0.3.0"]
[net.mikera/vectorz-clj "0.47.0"]
[distributions "0.1.2"]

;; Statistical dependencies
[incanter/incanter-core "1.9.2"]
[incanter/incanter-charts "1.9.2"]
[incanter/incanter-excel "1.9.2"]

With best regards
