Cheers!Hands-on real-world examples, research, tutorials, and cutting-edge techniques delivered Monday to Thursday. Below was the given description :In the train and test data, features that belong to similar groupings are tagged as such in the feature names (e.g., ind, reg, car, calc). Explore and run machine learning code with Kaggle Notebooks | Using data from House Prices: Advanced Regression Techniques. They hosted a The training set has around 600k observations and 59 features (including the target feature and an id feature) and test set has around 900K rows.

We will try to get some basic insights about the entire data.The detailed description of the features is given along with the dataset. Features without these designations are either continuous or ordinal. We can clearly observe that Size column has top value “Varies with device”looking over the plot we can observed that 1579 applications has more than 100000 installations.Wow, There are 10040 free applications in the given data set. 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. Prepare Train & Test Data Frames. As in different data projects, we'll first start diving into the data and build up our first intuitions. This was the first Kaggle competition that I participated. Make learning your daily ritual.Index(['MSSubClass', 'LotFrontage', 'LotArea', 'OverallQual', 'OverallCond',Index(['MSZoning', 'Street', 'Alley', 'LotShape', 'LandContour', 'Utilities',

In addition, feature names include the postfix bin to indicate binary features and cat to indicate categorical features. We can verify by checking the frequency of the top occurring category of the features.As shown above, the features ‘Utilities’, ‘Street’, ‘Condition2’, ‘RoofMatl’, ‘Heating’ are highly skewed (since they are having a single entry around 1400 times out of 1428 examples).

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. 1.

We can used different kind of plot to draw (corresponds to the name of a categorical plotting function)Options are: “point”, “bar”, “strip”, “swarm”, “box”, or “violin”. This happens due to many reasons such as unavailability of data, wrong entry of data, etc. It provides a high-level interface for drawing attractive and informative statistical graphics.Following are the common used seaborn visualisation :-A scatter plot is a set of points plotted on a horizontal and vertical axes.Scatter plot below shows the relationship between the passenger age and passenger fare based on pclass (Ticket class) from data taken from Titanic datasetBox plot is a simple way of representing statistical data on a plot in which a rectangle is drawn to represent the second and third quartiles, usually with a vertical line inside to indicate the median value. It is an approach to analyzing data sets to summarize their main characteristics, often with visual methods.The best EDA gives the interesting results about your data.Lets get into the problem with out any delay. 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. Let’s divide our features in train_df into each of those.Let’s see how the data in numerical features are distributed. We can replace them with their mean value using the inbuilt reputation functions from sklearn.After replacing, we can check once again for any missing values in numeric features:As we can see, we have handled all the missing values in the numeric features in the training data. We can decide on which one to remove by looking into its contribution to the target variable SalePrice. Cleaning : we'll fill in missing values. 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. We saw earlier correlation matrix shows the same with 0.64 value between Installs and Reviews.

Brief info is obtained.We can see that the train dataset consists of 80 features in total including the target variable SalePrice and 1460 training examples. EDA provides a lot of crucial information that is very easy to miss, information that helps that analysis in the long run.There are no hard-bound rules on how to perform EDA. The Kaggle community is incredibly supportive and is a great place to not only learn new techniques and skills, but also to challenge yourself to improve. So which results more applications has price value zero. This Exploratory analysis is based on the “Google play store Apps” kaggle data sets. Everyone dealing with the data has to find their own way of performing EDA and understand the data accordingly. Exploratory Data Analysis or EDA refers to the process of knowing more about the data in hand and preparing it for modeling.

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.

Data testing and Sampling technique 3. explore. Using Pandas, I imported the CSV files as data frames.
