A model own summary is a summary of a model that you have created or used. A model is a representation of something, such as a system, a process, or a phenomenon. A model summary should include the following information:
The name and type of the model
The purpose and scope of the model
The main features and functions of the model
The data sources and methods used to create or use the model
The results and outputs of the model
The limitations and challenges of the model
The future improvements or extensions of the model
For example, if you have created a linear regression model to predict preference rankings based on five predictors, you could write a model summary like this:
**Model Summary**
This is a linear regression model that predicts preference rankings based on five predictors: age, gender, income, education, and occupation. The purpose of this model is to analyze how these factors influence consumer behavior in different markets. The scope of this model is limited to one country (India) and one product category (clothing).
The main features and functions of this model are:
It uses a standard approach for describing the relationships between the predictors and the response variable (preference rankings).
It uses five predictors: age, gender, income, education, and occupation.
It uses linear regression to estimate the coefficients that best fit the data.
It uses R2 as the most common measure of how well the model fits the data. R2 represents how much of the variance in the preference rankings is explained by the predictors. A higher R2 indicates a better fit.
The data sources and methods used to create or use this model are:
The data was collected from online surveys conducted among 1,000 consumers in India.
The data was cleaned, transformed, and split into training and testing sets.
The training set was used to fit the linear regression model using SPSS software.
The testing set was used to evaluate the performance of the linear regression model using R2.
The results and outputs of this model are:
The linear regression model has an R2 of 0.707, indicating that approximately 71% of the variance in preference rankings is explained by age, gender, income, education, and occupation.
The coefficients estimated by the linear regression model are: age = 0.12; gender = -0.03; income = 0.25; education = -0.01; occupation = 0.08.
The predicted preference rankings for each consumer based on their age group are: 18–24 = 3; 25–34 = 4; 35–44 = 5; 45–54 = 6; 55+ = 7.
The limitations and challenges of this model are:
The sample size is relatively small (1000 consumers), which may affect the accuracy and generalizability of the results.
The variables used in this model may not capture all aspects of consumer behavior or preferences.
The linear regression approach may not be suitable for complex or nonlinear relationships between variables.
The future improvements or extensions of this model are:
to increase the sample size by conducting more surveys or using other sources of data.
to explore other types of models that may better fit complex or nonlinear relationships between variables.
to include more variables that may influence consumer behavior or preferences.
