It involves using Python libraries to inspect, summarize, and visualize data to uncover trends, patterns, and relationships. Here’s a breakdown of the key steps in performing EDA with Python: 1. Importing Libraries: Skewness is a statistical measure of the asymmetry of a probability distribution. It characterizes the extent to which the distribution of a set of values deviates from a normal distribution. Skewness between -0.5 and 0.5 is symmetrical. Kurtosis determines whether the data exhibits a heavy-tailed or light-tailed distribution.These methods are usually computationally very expensive. Some common examples of wrapper methods are forward feature selection, backward feature elimination, recursive feature elimination, etc. Forward Selection: Forward selection is an iterative method in which we start with having no feature in the model.Univariate Analysis.
