Assumptions to be considered for success with linear-regression analysis: For each variable: Consider the number of valid cases, mean and standard deviation. For each model: Consider regression coefficients, c
It helps to examine how changes in the independent variables impact the dependent variable. By fitting a mathematical model to the data, regression allows us to make predictions or estimate values for the dependent variable. This is based on the values of the independent variables. It is widely ...
What does s.t. mean in linear programming? Describe an application of linear programming in the real world. How do you know if a linear program is unbounded? What is a non linear function? What is the linear relationship between 4x + 6y = 12 and 2x + 3y = 6?

The computation behind the training process consumes a lot of time, so does the classification process. This can be a real test of our patience and the machine’s efficiency. As this learning method cannot handle huge amounts of data, the machine has to learn itself from the training data....
Statistics: How can I pool data (and perform Chow tests) in linear regression without constraining the residual variances to be equal? (Updated 26 June 2017) Statistics: Why do I get the error message "outcome does not vary" when I perform a logistic or logit regression? (Updated 26 June...
"Regression" in statistics is a method applied in investing, finance, and other areas that try to assess the nature and strength of relationships between the dependent and independent variable(s). It enables us to value assets and understand the connections between variables like stocks ...
R2 0.303 Adj-R2 0.302 RMSE 0.168 Notes: This table presents non-linear regression results with the mean greenwashing severity scores as the dependent variable and the selected independent variables to calculate the greenwashing risk ([0,1]), following the model approach by Dorfleitner and Utz...
The coefficient of the exponential decay function is changed incrementally from 1 × 10−4 to 1.5 (with step length 1 × 10−4) in this process, until the R2 is maximized3. The rationale for using a grid search that the process will find the weight of distant opportunities that best ...
