Hello I try to consctruct the AugmentedDickeyFuller object but i always have a “java.lang.NullPointerException” return.
I use this constructor : AugmentedDickeyFuller stationarite = new AugmentedDickeyFuller(residu.getVals());
Where residu.getVals() is an array of double not null.
My var “stationarite” is alwais null, anybody can tell me why or how to use this method correctly ?
Thanks
