How to deal with hierarchical / nested data in machine?
Other than the tree-based methods, there is a method based on SVM. For random-forest-based method, you can try MixRF () in our R package MixRF on CRAN. Given that you only have two variables and straightforward nesting, I would echo the comments of others mentioning a hierarchical Bayes model.
Is the multiindex a hierarchical representation of the data?
Notice that the MultiIndex contains multiple levels of indexing–in this case, the state names and the years, as well as multiple labels for each data point which encode these levels. If we re-index our series with this MultiIndex, we see the hierarchical representation of the data:
How are columns used in hierarchical indexing in Python?
Remember that columns are primary in a DataFrame, and the syntax used for multiply indexed Series applies to the columns. For example, we can recover Guido’s heart rate data with a simple operation: Also, as with the single-index case, we can use the loc, iloc, and ix indexers introduced in Data Indexing and Selection.
How is hierarchical indexing used in data science?
This is fundamentally four-dimensional data, where the dimensions are the subject, the measurement type, the year, and the visit number. With this in place we can, for example, index the top-level column by the person’s name and get a full DataFrame containing just that person’s information:
How to create a nested list in Dataframe?
Create dataframe using data.frame function with the do.call and cbind. cbind is used to bind the lists together by column into data frame. do.call is used to bind the cbind and the nested list together as a single argument in the Data frame function. Also, store the whole data frame in a variable named data_frame and print the variable.

How to convert a list to a data frame?
Method 1: To convert nested list to Data Frame by column. Create dataframe using data.frame function with the do.call and cbind. cbind is used to bind the lists together by column into data frame. do.call is used to bind the cbind and the nested list together as a single argument in the Data frame function.
