How to find the regression model which expresses the relationship between adsorption and process variables for the predicting fluoride removal (%)?

You can find a regression model that effectively between adsorption and process variables by collect data and analyze it to determine the relationship and destribution, then using the relevant variables such as stepwise regration or correlation.select a model ( linear ,non linear or polynomial ) regration then testing data by fitting the model. To evaluate this model you applying mean square error technique and taking various features to get and improve the accuacy and to get good results.

To find the regression model that expresses the relationship between adsorption and process variables for predicting fluoride removal (%), you can follow these steps:

Collect Data: Gather data on adsorption levels, process variables, and corresponding fluoride removal percentages. Make sure you have a dataset with sufficient observations to analyze the relationship.

Identify Potential Variables: Identify the process variables that may influence adsorption and fluoride removal. These variables could include factors such as pH, temperature, contact time, adsorbent dosage, etc.

Perform Regression Analysis: a. Choose a Regression Model: Decide on the type of regression model to use based on the nature of your data. For example, you could use simple linear regression if there is a single predictor variable or multiple linear regression if there are multiple predictor variables.b. Fit the Regression Model: Use statistical software (e.g., R, Python, SPSS) to fit the regression model to your data. The regression model will estimate the coefficients that represent the relationship between the predictor variables (process variables) and the response variable (fluoride removal %).c. Assess Model Fit: Evaluate the goodness of fit of the regression model by examining metrics such as R-squared, adjusted R-squared, F-test, and p-values of coefficients. These measures help you understand how well the model explains the variation in fluoride removal percentages.d. Interpret Results: Interpret the coefficients of the regression model to understand the direction and strength of the relationships between the process variables and fluoride removal %. Positive coefficients indicate a positive relationship, while negative coefficients indicate a negative relationship.

Validate the Model: Once you have developed the regression model, validate it using techniques such as cross-validation or split-sample validation to ensure its reliability and generalizability.

Use the Model for Prediction: Once you have a validated regression model, you can use it to predict fluoride removal % based on the values of the process variables. Plug in the values of the process variables into the regression equation to estimate the expected fluoride removal %.

By following these steps, you can find a regression model that effectively captures the relationship between adsorption, process variables, and fluoride removal %, allowing you to predict fluoride removal based on the chosen process variables.

Dear, I am sending you my work, which can serve as a possible indicator for determining the most suitable regression model. The paper deals with a regression model that describes the embryonic and post-embryonic growth of the pond snail Lymnaea stagnalis.
