Multivariate Analysis

Multivariate Analysis is a statistical technique that analyzes multiple variables to understand the relationships, patterns, and interactions between them. It can provide deep insights that can significantly influence business strategies, improve predictions, and drive more informed decision-making.

Multivariate analysis is a set of statistical techniques used for analysis of data that contain more than one variable.

Multivariate analysis is used widely in many industries, like healthcare. In the recent event of COVID-19, a team of data scientists predicted that Delhi would have more than 5lakh COVID-19 patients by the end of July 2020. This analysis was based on multiple variables like government decision, public behavior, population, occupation, public transport, healthcare services, and overall immunity of the community.

Multivariate Analysis Techniques

Multivariate Analysis includes several statistical techniques to analyze data that consists of multiple variables or features. Here are some commonly used Multivariate Analysis Techniques:

Multiple Regression: This method explores the relationship between two or more features and a response by fitting a linear equation to observed data.
Principal Component Analysis (PCA): This method reduces the dimensionality of the data by transforming the original variables into a new set of variables known as the Principal Components.
Factor Analysis: This method is used to find hidden or latent variables in a dataset. It helps to identify underlying factors that explain the pattern of correlations within a set of observed variables.
Discriminant Analysis: This method is used to analyze the difference between two or more groups of data based on the classification of variable categories.
Cluster Analysis: This method classifies objects or cases into several groups or clusters so that cases within each cluster are more similar to each other than those in other clusters.
Canonical Correlation Analysis (CCA): This method is used to understand the relationship between two sets of variables. It finds the correlation between linear combinations of variables from each set.
Manifold Learning: Techniques like t-SNE (t-Distributed Stochastic Neighbor Embedding) and UMAP (Uniform Manifold Approximation and Projection) are used to visualize high-dimensional data in two or three dimensions, often revealing hidden patterns.
Multivariate Analysis of Variance (MANOVA): This method extends the ANOVA to include multiple continuous dependent variables, testing for differences in multiple output variables simultaneously.
Multivariate Adaptive Regression Splines (MARS): This technique builds flexible models by fitting piecewise linear regressions.

Each of these techniques has specific use-cases and is chosen based on the type of data at hand, the business question being answered, and the specific use case.

The Objective of multivariate analysis

Multivariate analysis has several objectives that span across multiple fields and use-cases. The most common objectives are:

Understanding Relationships: Multivariate analysis helps in understanding and interpreting the complex relationships between multiple variables in a dataset. By analyzing these relationships, we can get valuable insights about the structure and dynamics of the dataset.
Dimension Reduction: In a dataset with many variables, some of the variables might be correlated. Multivariate analysis techniques like Principal Component Analysis (PCA) can reduce the dimensionality of the dataset by creating new uncorrelated variables that successively maximize variance.
Prediction and Classification: Multivariate analysis helps in predicting the values of certain variables based on the values of others. Techniques like Multiple Regression, Discriminant Analysis, and Support Vector Machines can be used for prediction and classification tasks.
Data Compression: Multivariate analysis can be used to compress data by reducing a large set of variables to a smaller set that still contains most of the information in the original set. This can be very useful for visualizing and understanding high-dimensional datasets.
Hypothesis Testing: Techniques such as MANOVA (Multivariate Analysis of Variance) can be used to test hypotheses about means of several dependent variables across groups.
Pattern Recognition: Techniques such as Cluster Analysis can be used to recognize and categorize patterns within the data.
Optimizing Response Variables: Multivariate analysis can help in situations where the goal is to optimize more than one response variable.

By achieving these objectives, multivariate analysis allows businesses, researchers, and analysts to make more informed and effective decisions.
