What is weighted residual method?
In estimating a linear relationship using ordinary least squares (OLS), the regression estimates are such that the sums of squares of the residuals are minimised. This method treats all residuals as being as important as others.There may be reasons why the treatment of all residuals in the same way may not be appropriate. One possibility is that there is reason to believe that there is a systematic trend in the size of the error term (residual). One way to compensate for such heteroscedasticity is to give less weight to the residual when the residual is expected to be larger. So, in the regression calculations, rather than minimise the sum of squares of the residuals, what is minimised is their weighted sum of squares.
What is the addition or subtraction method?
Column method can be used for both !
Is it possible for you to use trial and error method or the X-method to factor the difference of two squares?
No it is not. At least, not sensibly.
What is the difference between finite element method and Ritz method?
The main difference between the Rayleigh-Ritz method (RRM) and the finite element method lies in the definition of the basis functions. For FEM, these are element-related functions, whereas for RRM these are valid for the whole domain and have to fit the boundary conditions. The Rayleigh-Ritz method for homogeneous boundary conditions leads to the same discretized equations as the Galerkin method of weighted residuals.

What is the column method?
is this the column method for addition / subtraction or the column method for multiplication?? The term column method simply means to stack in columns so that the units; tens and hundreds are all lined up.
What is a compact method in maths?
compact method is another word for column method
What is the addition or subtraction method?
Column method can be used for both !
What is the easist method to select a column in Excel?
Click on the letter at the top of the column; that will select the entire column.
What is the name of the method for drawing a trend line for the data in a scatterplot?
There are many methods, though the most popular is the method of least squares. This method minimises the sum of the squares of the vertical distances between each point and the corresponding point on the line.
