Being a highly adaptable programming language, Python allows easy developing and maintaining projects of different complication. Python has been an important part of Google from the company’s beginning. Python is recognized as an official language at Google, it is one of the key languages at Google today, alongside with C++ and Java. Some of the key Python contributors are Googlers and they continue to use, promote, and support the language actively. Simple and Multiple Linear Regression in Python. There are two main ways to perform linear regression in Python — with Statsmodels and scikit-learn.

Simple and Multiple Linear Regression in Python

It is also possible to use the Scipy library, but I feel this is not as common as the two other libraries I’ve mentioned. Let’s look into doing linear regression in both of them: Linear Regression in Statsmodels Statsmodels is “a Python module that provides classes and functions for the estimation of many different statistical models, as well as for conducting statistical tests, and statistical data exploration.” (from the documentation) As in with Pandas and NumPy, the easiest way to get or install Statsmodels is through the Anaconda package. Import statsmodels.api as sm Let’s see how to actually use Statsmodels for linear regression. First, we import a dataset from sklearn (the other library I’ve mentioned): Linear Regression (Python Implementation) This article discusses the basics of linear regression and its implementation in Python programming language.

Linear Regression (Python Implementation)

Linear regression is a statistical approach for modelling relationship between a dependent variable with a given set of independent variables. Note: In this article, we refer dependent variables as response and independent variables as features for simplicity. In order to provide a basic understanding of linear regression, we start with the most basic version of linear regression, i.e. Pythonic Data Cleaning With Pandas and NumPy. Data scientists spend a large amount of their time cleaning datasets and getting them down to a form with which they can work.

Pythonic Data Cleaning With Pandas and NumPy

In fact, a lot of data scientists argue that the initial steps of obtaining and cleaning data constitute 80% of the job. Therefore, if you are just stepping into this field or planning to step into this field, it is important to be able to deal with messy data, whether that means missing values, inconsistent formatting, malformed records, or nonsensical outliers.

In this tutorial, we’ll leverage Python’s Pandas and NumPy libraries to clean data. We’ll cover the following: Dropping unnecessary columns in a DataFrameChanging the index of a DataFrameUsing .str() methods to clean columnsUsing the DataFrame.applymap() function to clean the entire dataset, element-wiseRenaming columns to a more recognizable set of labelsSkipping unnecessary rows in a CSV file Here are the datasets that we will be using: Note: I recommend using Jupyter Notebooks to follow along. Great! Anaconda Distribution — Anaconda documentation.

Python Programming Tutorials. Welcome to a data analysis tutorial with Python and the Pandas data analysis library.

Python Programming Tutorials

The field of data analytics is quite large and what you might be aiming to do with it is likely to never match up exactly to any tutorial. With that in mind, I think the best way for us to approach learning data analysis with Python is simply by example. My plan here is to find some datasets and do some of the common data analysis tasks, using the Pandas package, to hopefully get you familiar enough with the package to work with it on your own.

To begin, let's make sure we're all on the same page. I will be using Python 3.7 and Pands 0.24.1 You can likely follow along with different versions of things, just know there may be minor differences that you will need to work out. Setting up your own Data Science workspace with Visual Studio Code and Anaconda (Python) Visual Studio Code is a free code editor that you can tailer to your needs.

Build a Predictive Model in 10 Minutes (using Python) End to End — Predictive model using Python framework. Predictive modeling is always a fun task. The major time spent is to understand what the business needs and then frame your problem. The next step is to tailor the solution to the needs. As we solve many problems, we understand that a framework can be used to build our first cut models. Not only this framework gives you faster results, it also helps you to plan for next steps based on the results. In this article, we will see how a Python based framework can be applied to a variety of predictive modeling tasks. Here is the link to the code. The framework discussed in this article are spread into 9 different areas and I linked them to where they fall in the CRISP DM process.

Learning Path: Python: Predictive Analysis with Python. Make predictions as a data scientist! In Detail Predictive analytics is the process of analyzing historical data to estimate the future results. Pandas and scikit-learn are popular open source Python packages that provide fast, high performance data structures for performing efficient data manipulation and analysis.
