**Definition:**

- It groups the similar data in same group.
- The goal of this procedure is that the objects in a group are similar to one another and are different from the objects in other groups.
- Greater the similarity within a group and greater difference between the groups, more distinct the clustering.
- Cluster analysis provides a potential relationship and construct systematic structure in large number of varables and observations.

Main objectives of clustering are: (more…)

Linear regression makes several key assumptions: Linear relationship Multivariate normality No or little multicollinearity No auto-correlation Homoscedasticity Linear regression needs at least 2 variables of metric (ratio or interval) scale. …

Before we build stats/machine learning models, it is a good practice to understand which predictors are significant and have an impact on the response variable. In this post we deal…

Hello guys, we have learnt about Linear Regression model in my previous article. Today, in this article we will get to learn the basics of Logistic Regression and some tricks to find the relation between the variables.

Do you know what type of variable is used in logistic regression… Don’t worry, if you don’t (more…)

Introduction Variable selection is an important aspect of model building which every analyst must learn. After all, it helps in building predictive models free from correlated variables, biases and unwanted…
