Libgee is a utility library providing GObject-based interfaces and classes for commonly used data structures. Do **NOT** use this tag for referring to Google Earth Engine or generalized estimating equations.

Overview

Libgee is an utility library providing GObject-based interfaces and classes for commonly used data structures.

Libgee provides the following interfaces:

  • Travsersable
  • Iterable
  • Collection
  • List
  • BidirList
  • Set
  • SortedSet
  • BidirSortedSet
  • MultiSet
  • Queue
  • Deque
  • Map
  • SortedMap
  • BidirSortedMap
  • Iterator
  • BidirIterator
  • BidirListIterator
  • ListIterator
  • BidirListIterator
  • MultiMap
  • Future

The ArrayList, ArrayQueue ConcurrentLinkedList, ConcurrentSet, HashSet, HashMap, HashMultiSet, HashMultiMap, LinkedList, PriorityQueue, Promise, TreeSet, TreeMap, TreeMultiSet, and TreeMultiMap classes provide a reasonable sample implementation of those interfaces. In addition, a set of abstract classes are provided to ease the implementation of new collections.

Around that, the API provide means to retrieve read-only views, efficient sort algorithms, simple, bi-directional or index-based mutable iterators depending on the collection type.

Libgee is written in Vala and can be used like any GObject-based C library. It's planned to provide bindings for further languages.

Tag usage

Do NOT use tag for referring to Google Earth Engine. Use the tag instead.
Do NOT use tag for referring to Generalized Estimating Equations. Use alternative tags, instead.
If the question is about Generalized Estimating Equations, consider whether it is more suitable on Stack Overflow SE or Cross Validated SE, the Stack Exchange site for statistics, machine learning and data analysis.

Google Earth Engine (GEE): add a character in multiple bands name

I have two images with the same band names (imageA and imageB) and I am going to merge them into a single image. I need to add a character that identifies the name of the bands (for example, B2_medianA and B2_medianB for imageA and imageB). It's…

For loop over 'ee.image.Image' with 'ee.ee_list.List' of bands with Earth Engine Python API in Colab

I want to use a function to scale the bands of an image. The number and name of the image bands may differ. The following (working) code almost does what I want, except I want to loop over the (number of) bandnames, instead of a pre-defined range…

Has anyone ever compared results from R geepack, Python statsmodels, and SPSS Generalized Estimating Equations?

I ran my dataset through these 3 platforms and got wildly different results (i.e. very different p-values) although the calculated means and SDs were the same. This hints that it should not be due to missing data.
