easyPLS

Introduction: 

  • Partial Least Squares (PLS) is a statistical technique used for regression modeling in which the quantitative relationship between the predictor variables known as independent variables and the response variable known as the dependent variable is modeled in a way that accounts for the correlation between the predictor variables.
  • Our cloud SaaS Platform will provide you a web-based solution useful if data has a high degree of multicollinearity within the factors and you need quantitative predictions from the model.
  • A SaaS Cloud Platform will be provided to the user for data analytics anytime, anywhere.

Why choose the easyPLS Algorithm? 

  • Multicollinearity handling: PLS is able to handle multicollinearity, which is the high correlation between predictor variables. This is because PLS reduces the dimensionality of the predictor variables into a smaller set of uncorrelated latent variables or components, which capture the maximum variation in the predictor variables while also explaining the maximum variation in the response variable.
  • Improved predictive accuracy: PLS can improve predictive accuracy compared to other linear regression techniques, such as ordinary least squares (OLS), when many predictor variables are highly correlated with each other and the response variable. This is because PLS models the relationship between the predictor variables and the response variable in a way that maximizes the covariance between them.
  • Nonlinear modeling: PLS can be used for nonlinear modeling, where the relationship between the predictor variables and the response variable is nonlinear. This is achieved by transforming the predictor variables into a higher-dimensional space, where the relationship between the predictor variables and the response variable is linear.
  • Variable selection: PLS can be used for variable selection, where only the most relevant predictor variables are selected for the model. This can reduce the complexity of the model and improve the interpretability of the results.
  • Robustness: PLS is a robust technique that is less sensitive to outliers and missing data compared to other regression techniques. This is because PLS uses a soft modelling approach that accounts for the noise in the data.
  • Interpretable results: PLS produces results that are easy to interpret and explain. This is because PLS reduces the dimensionality of the predictor variables into a smaller set of uncorrelated latent variables or components, which can be visualized and analyzed. Additionally, PLS can be used for variable selection, which can further improve the interpretability of the results.
