Stata Notebook Example

Working with Stata in Jupyter

You can work with a Jupyter notebook using Stata just as you would using Python. Text and math can be written in Markdown as we have done in the other notebooks. So, use your usual Stata code in code cells, produce figures etc., as if you were in the Stata more ...


Stata in Python Notebook

Stata in a Python Jupyter Notebook

You can work with Stata in a Python notebook by using the package ipystata. Just like r2py, which allows us to use R in Python, we can now use both (or if you want all three!) programming languages in one notebook.

Setup

Let's start by importing all the packages we want to use.

Dynamic Programming in Python

Introduction to Dynamic Programming

We have studied the theory of dynamic programming in discrete time under certainty. Let's review what we know so far, so that we can start thinking about how to take to the computer.

The Problem

We want to find a sequence $\{x_t\}_{t=0}^\infty$ and a function $V^*:X\to\mathbb{R}$ such that

$$V^{\ast}\left(x_{0}\right)=\sup\limits _{\left\{ x_{t}\right\} _{t=0}^{\infty}}\sum\limits _{t=0}^{\infty}\beta^{t}U(x_{t},x_{t+1})$$

Faster Dynamic Programming with Numba

Faster Computations with Numba

Some notes mostly for myself, but could be useful to you

Altough Python is fast compared to other high-level languages, it still is not as fast as C, C++ or Fortran. Luckily, two open source projects Numba and Cython can be used to speed-up computations. Numba is sponsored by the producer of Anaconda more ...


Economic Data Analysis in Python

Working with Economic data in Python

This notebook will introduce you to working with data in Python. You will use packages like Numpy to manipulate, work and do computations with arrays, matrices, and such, and anipulate data (see my Introduction to Python). But given the needs of economists (and other scientists) it will be advantageous for us to use pandas more ...



GIS with QGIS

Using Geographic Information Systems (GIS) in QGIS and Python

Geographic Information Systems (GIS)

GIS refers to methods of storing, displaying and analyzing geogaphical information. These methods have become essential in economic analysis (as you have noticed from the reading list for our Ph.D. course on economic growth). For this reason, it is good that you acquaint yourself with these methods. They will prove very useful when doing research, especially to show the spatial distribution of your variables of interest, contructing new measures, or doing spatial analysis.

Introduction to Python

Introduction to Python and IPython using Jupyter

Python is a powerful and easy to use programming language. It has a large community of developers and given its open source nature, you can find many solutions, scripts, and help all over the web. It is easy to learn and code, and faster than other high-level programming languages...and did I mention it is free more ...
