The target columns signifies whether or not a claim was filed for that policy holder.Remaining 26 features are either continuous or ordinal are have been plotted belowThis post has already crossed a 10 mins read, so I will stop here and write another post to continue with the EDA. Explore and run machine learning code with Kaggle Notebooks | Using data from House Prices: Advanced Regression Techniques.
The test or prediction dataset consists of 79 features (SalePrice is to be predicted) and 1459 data-points.Any data set will contain certain missing values in its features, be it numerical features or categorical features. In addition, feature names include the postfix bin to indicate binary features and cat to indicate categorical features. Then load the data set.
We can use the same method used in the training set to replace them with their respective mean values.Checking again for any missing values after replacing:So, we have finished dealing with all the missing values in the numerical features in both the train and test dataset.Let’s now look into the distribution of categorical features.We can see that some of the features are totally skewed. Introduction: Exploratory Data Analysis or EDA refers to the process of knowing more about the data in hand and preparing it for modeling. As in different data projects, we'll first start diving into the data and build up our first intuitions. This Exploratory analysis is based on the “Google play store Apps” kaggle data sets. Exploratory Analysis This first notebook is designed to get familiar with the problem at hand and devise a strategy for moving forward.
Search. This Exploratory analysis is based on the “Google play store Apps” kaggle data sets. Porto Seguro is Brazilian insurance company. The dots outside the blue box depicts the data-points that pose as outliers.We could also plot the features along with the target variable to do bivariate analysis.
We can simply drop that row to avoid bad results from the data model.The word “univariate” itself indicates that analysis on the each one columns.Lets do that quickly to get more interesting results.Before that we observed Size, Installs and Price columns contained symbols ‘$’,’+’,’M’,’k’. How the Rating varies depends on the Category.Clearly we can see the ‘Education’ has the high rating and ‘Dating’ is the least rating Categories.Above plot gave that ‘Finance’ Category applications has the high prices compared to others.“Game” Category has the highest reviews followed by “Communication” and “Sports”.Clearly plot shows that Gaming Category applications installed highest number followed by Communication.Note: From the above two plots observed that as more number of installs results the increase in the reviews count as well. Checking for testing dataAround nine features are having missing values. 14 min read. Exploratory Data Analysis (EDA) is an approach to analysing data sets to summarize their main characteristics, often with visual methods.Following are the different steps involved in EDA : Data Collection; Data Cleaning; Data Preprocessing; Data Visualisation; Data Collection. Notebooks. Below is the count of how many missing values in each columns.Interesting thing that only Rating has more number(1474) of missing values whereas Type and Content Rating has only 1.To visualize the missing data values as below using heatmap() method.We observed that Rating has more missing values and heat map shows the same as well.Here I filled the missing values with mean or top value of the each column to get best results.To know the mean, top values for each columns as below using describe().Rating column has mean value with 4.1, Type column has top value “Free” and Content Rating has “Everyone”Before that lets remove the space between the Content and Rating in the column name “Content Rating” which results error while performing any operation on it.Yes, it has only one row.

We need to remove those to get better accuracy. The distplot gives us the univariate distribution plot of each variable as shown below. In this post, I will do an exploratory analysis of the training data and also try some statistical inference tests. We learnt how to detect outliers using these plots and how to remove them. Prepare Train & Test Data Frames. Make learning your daily ritual.Index(['MSSubClass', 'LotFrontage', 'LotArea', 'OverallQual', 'OverallCond',Index(['MSZoning', 'Street', 'Alley', 'LotShape', 'LandContour', 'Utilities', If you have time, I would recommend to go through multiple notebooks and fork down the methods to implement them in your own notebook. search. For model training, I started with 17 features as shown below, which include Survived and PassengerId. A Data Science approach to predict the best target for a marketing campaign. Kudos to Hands-on real-world examples, research, tutorials, and cutting-edge techniques delivered Monday to Thursday. Cleaning : we'll fill in missing values. They hosted a Kaggle competition in Nov 2017 to predict the probability that a driver will initiate an auto insurance claim in the next year.
This happens due to many reasons such as unavailability of data, wrong entry of data, etc. The lower and upper quartiles are shown as horizontal lines either side of the rectangle.Box plot below shows how the passenger fare varies based on ticket class.A histogram is an accurate representation of the distribution of numerical data.
