How to use AugmentedDickeyFuller object in suanShu ?

[hessinemaaoui]

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
