##### Transport Mode Analysis with SVM Mode
The attached data has records of 444 employees in a firm. The variables are described below: -Build a model that best explains the employee's decision to use cars as the main means of transport? What would your predictions regarding their choice of transport be for the following two employees? The model explains how response variable with multi level values is being dealt with SVM and multinon regression
##### Employee Retaintion Analysis
This solution explains how logistic regression and further regularization is used to develop a simple model for predicting employee retention.
##### Time Series Analysis of Sales
This solution explains how HoltWinter method and ARIMA mode can be used for prediction
##### KNN R, K-NEAREST NEIGHBOR IMPLEMENTATION IN R USING CARET PACKAGE
In this solution, I am going to build a Knn classifier using R programming language. Will use the R machine learning caret package to build our Knn classifier. The most commonly used distance measure is Euclidean distance. The Euclidean distance is also known as simply distance. The usage of Euclidean distance measure is highly recommended when data is dense or continuous. Euclidean distance is the best proximity measure.

##### Analysis of Two sample and understanding of their difference
This analysis shows how we can compare two different sample and conclude whether they are having similar mean or not by using insurance sales data of two separate insurance..
##### Loan Approval Prediction Model
Company wants to automate the loan eligibility process (real time) based on customer detail provided while filling online application form. These details are Gender, Marital Status, Education, Number of Dependents, Income, Loan Amount, Credit History and others. To automate this process, they have given a problem to identify the customers segments, those are eligible for loan amount so that they can specifically target these customers. Here they have provided a partial data set. Problem link is https://datahack.analyticsvidhya.com/contest/practice-problem-loan-prediction-iii/
