variable technique
least square technique
indexed technique
fixed technique
Answer is Right!
Answer is Wrong!
The correct answer is B. least square technique.
Least squares is a statistical method for estimating the values of parameters in a linear regression model. The method minimizes the sum of the squares of the vertical distances between the observed values and the values predicted by the model.
The other options are incorrect.
- Variable technique is not a valid term in statistics.
- Indexed technique is a method for estimating the parameters of a linear regression model that uses a set of indexes to represent the data points.
- Fixed technique is a method for estimating the parameters of a linear regression model that uses a set of fixed values to represent the data points.
