It’s no surprise that ML has become the biggest trend in the technical and analytical hub, breaking down barriers on its path.

However, it would only be feasible because Machine Learning is made up of incredible tools and approaches that help to launch ML into the market and give it the strength to support outstanding applications in a variety of fields.

There are several sorts of regression to do, each with its own set of characteristics and situations under which it is best used.

Even though people end up learning with these two prominent ML algorithms since they are only two forms of regression, linear and logistic regressions are usually the first ideas that spring to mind when talking about regression approaches in data science.

For studying or examining the relationship between the dependent and independent set of variables, the most extensively used regression techniques are applied.

It is a broad word that encompasses a wide range of data analysis techniques used in qualitative-exploratory research to analyze infinite variables and is mostly used for forecasting, time series analysis modeling, and determining cause-effect correlations.

Among all sorts of regression studies, five types of regression procedures are commonly utilized for difficult issues.

  • Regression analyses are used to determine the probable link between distinct variables. So they are used to figure out how changes in an independent variable affect the dependent variable.

Regression techniques

Logistic regression – It is recommended when the response variable is binary, it forecasts the parameters of a logistics system, and it is commonly used to examine categorical data in the form of binomial regression.

The link between the dependent and independent variables is computed by utilizing the logit function to compute probabilities.

Ridge regression – It is used to analyze a large number of regression data sets. When multicollinearity occurs, least-square calculations become unbiased, and the regression calculations are given a bias degree, resulting in a decrease in standard errors using ridge regression.

Because the model comprises correlated featured variables, ridge regression is utilized as a remedial strategy to reduce collinearity between predictors. As a result, the final model is limited and inflexible in its maximum approach.

Linear regression – It’s the most basic regression strategy for predictive analysis, a linear approach that emphasizes the relationship between the answer and the predictors or descriptive variables. It primarily addresses the response’s conditional probability distribution and the predictor’s applications.

Polynomial regression – The polynomial regression approach is used to execute a model that is fit to manage non-linearly separated data. The best-fitted line isn’t a straight line in this case; instead, it’s a curve that best fits the data points.

It is commonly used to fit curved data and is best suited for least-squares approaches. It focuses on predicting the dependent variable (Y) anticipated value in relation to the independent variable (x).

Lasso– It’s a frequently used regression methodology that does both regularization and selection. It employs simple shielding and selects a set of variables for the final model’s implementation.

Lasso Regression decreases the number of dependent variables; similarly, if the penalty term is large in ridge regression, coefficients can be lowered to zero, making feature selection easier. It’s referred to as L1 regularization.


In a word, regression analysis is a combination of statistical tools and procedures that allows one to create a predicted mathematical equation between creative influences and performance results while also demonstrating the causal-effect relationship.

Furthermore, the choice of the best regression approach is totally dependent on the data and requirements to be met.
