            You are not initialising your second class, you are not initialising your 'product' variable to access the list in your model class. It is indeed set to null. To fix this, first create an instance of the model class 'Products' and then using that instance variable, access the list in the class. Assign that list to a variable and use that in your UI. Also, it is recommended that you declare your variables outside the 'build' method because the build methods runs every time the UI needs to be refreshed, which could potentially reset your values. This may not be the desired behaviour, but that depends on the application.

            To access the list inside your class, you first need to create an instance of that class like this:

            .scatter() funciton takes float or array-like of x and y coordinates. As these are coordinates they are supposed to be in pairs and therefore x and y should be of equal length. In your code x is clf.support_vectors_[:0] and y is clf.support_vectors_[:1]. The syntax iterator[:k] says that we should pick every element in the iterator until the k-th element which we should not pick. So when we combine these things together we can spot that x and y have different lengths and therefore throw an error.

            Meteor Blaze helper and Mongo collection.find with Session key selector
            Asked 2021-May-08 at 18:03

            This Meteor code uses Meteor Blaze template helper that supplies some html elements with data from mongo collection.

            The collection.findOne has Session.get as the selector so that when there is no value for the Session key then I get an empty object to the template so that I get no data i.e. blank element. But I still get values in some elements. mainly the editable div and span and one input elements as commented in the html file.

            Where did I go wrong? I am trying to clean the "form" when I fire an event by setting the Session.set('plate', '') i.e. blank value for the session key 'plate', empty object, no data for the Blaze template, clears the elements, right? Thank you

            it happens because you use * operator instead of + difference between them is:

            * - 0 or more of the preceding expression

            + - 1 or more of the preceding expression

            so in your case * operator takes this empty space as "0 or more" and thinks, that it is a separate element, expression, that you probably want is:

            multilevel stan model with three hierarchies
            Asked 2021-May-06 at 09:24

            Assume I have a multilevel structure of data. With a global distribution, from which I draw a highlevel distribution from which i draw a lowlevel distribution from which I draw my response variable. How would I implement such a thing in a stan model.

            Below is a minimal example which I hope illustrates the problem. In the stan code there is

            • one commented "model" section which is working, but ignores the mutlilevel aspect and treats every lower level equal, irrespective of the highlevel origin and provides therefor not shrinkage by the highlevel order (see pic).
            • A "model"section with a forloop, which I though would do what I want, but takes forever to finish, and with a lot of warnings (Rhat, treedepth, Bayesion Fraction, low ESS)

            I am quite inexperienced with modeling and all tutorials on ML-Modeling do not have the Loop-Approach I though would make sense here, so I suspect I am completely heading in the wrong direction with that. So any help will be highly appreciated.

            R-Code to generate and run the model

            You need to increase your media query selector accuracy, something like div#contact, div#vehicle { width: 100%; } instead of just div. The media query css works just fine, but gets overwritten by the more accurate one above (selecting by an element ID is more accurate than selecting by element types).
