Regression analysis is the data analytical tool. It is used by business people and data analysts to predict the data from the history of the data and This tool helps in decision-making and data science for the big companies.  That is statistical tools help to estimate the relationship between a dependent variable and an independent variable.  This does not have one independent variable, it can have multiple independent variables and there are various importance in analysis.  This is used in many contexts in business, finance, and economics and it is used in the stock market to help investors.

 Importance of the Regression Analysis

Predict the market’s future situation, using the historical data help to predict future business plans, marketing strategy, customer preferences and  Use the past year’s sales data to calculate the future sales condition.  Helps predict the investment plans for the new business.

Types of Regression Analysis

Simple Linear Regression

This model is most commonly used by all the departments. It is used by the linear relationship between the dependent and independent variables. There are two types of variables used, one is the independent variable and the other one is the dependent variable. This model is used to analyze the impact of the pricing of products, promotion of products, and marketing of products.  This is the statistical tool to analyse the marketing activities to regulate sales.

Logistic Regression Analysis.

This regression analysis is based on analysing the probability of two extremes yes or no.  It is used for two possible outcomes and the dependent variable is used for two possible outcomes. Logistic regression is based on the survey questions.  This model is used to analyze a particular type of binary data and it is used to predict. whether the customer will buy this product or not and find customers who have an interest in that product.

Polynomial Regression Analysis

This tool is used to analyse the data based on the curve lines or the linear lines through a calculated relationship between the dependent and independent variables. This analysis is a sophisticated calculating method, that can be used in multilevel feedback data. This tool is mostly used in the finance field. If a person wants to plan a budget for his income and wants to earn money for that income, this polynomial regression will help to predict the expenses and give a plan for the budget.

Stepwise regression analysis

This is the model used to step by step construct data to analyse. This method mostly recommended multiple variables for easy to select the variable without any human involvement. This stepwise regression method is a forward and backward method, both are used in research methods, but sometimes this method has a lack of accuracy.  Most of the statisticians used this stepwise regression before other regression analyses and this model used the medical data of one person to analyse the blood pressure.

Multiple linear regression

Multiple linear regression is similar to the simple linear regression and it is the relationship between two independent variables and one dependent variable. This analysis is mainly used for better accuracy of outcome data than other variables. This regression helps to understand the multiple-factor outcomes for the business. Multiple regression is used in a wide range of applications, for instance, it is used in business, marketing, and sales analyses, medical and technical analysis.  This tool helps to analyse a wide range of data to predict the outcome for different businesses.

What are the uses of regression analysis?

The predictive analysis

The regression analyses the predicting the various kinds of business outcomes and the predictions are nearly accurate to help the decision making and also help to avoid the risk. The finance, insurance, and economic-based analyse depend on the regression analysis.  This model uses the historical data for the past business to give the solution for the problem, usually, Most companies use this method to calculate the price strategy, marketing, and sales values. These predictions help companies to be more competitive in today’s business.

Enhance the business activities

If anyone wants to start a new business or any company launches a new product regression analysis can help to analyse previous data. Customer service data will help to analyse the product’s production, marketing situation, packaging, and distribution of the products.

Customer analysis also helps to improve sales and create a relationship between the customer and the company and this analysis helps to make regular buyers.

Increase the sales level

Most companies are often used for the regression analysis prediction of their company sales. because competition for sales in various companies is quite increasing steadily. So the largest companies are certain to use regression analysis and they are collecting past sales data, pricing structure, and advertising methods for predicting future sales levels. Hence they make their new product sales plan under this analysis.


Regression analysis gives various advantages at the business level and this is the statistical method for analysing the various types of data.  This is the scientific analysis for nowadays, most of the companies develop to help with these regression models. Researchers and scientists also use this model for their research and prediction of this analysis is more perfect.
