# When using the least squares method should the column of residuals always sums to zero?

Yes.

### 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… Read More

### What is the column method?

### 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.

### 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.

A non-communicable disease or NCD is a disease which is not infectious, therefore it does not have any method of transmission to other organisms.

### Do you put the lower number on the bottom in column method?

You put the lower number at the bottom idiot you know nothing!

### Can a linear trend line can be obtained by using a least square method rather than a scatter diagram method?

A scatter diagram will give a quick but rough extimate of the trend line - especially if there is a lot of variation about the trend. The least squares method will be more accurate.

### What is the meaning or definition of word method in scientific method?

it always leads to the solution of the problem.

### What is quincunx method?

Quincunx method - this is like square method with a tree placed in the center of each of the squares. Some variations may be done by planting the trees closer together in rows rather than having the rows apart. Trees planted at the center are temporary or fillers.

### How do you select hplc column in method development?

firs you mist know the polarity for sample, wen the sample polar you can use "RP" column like C18 or C8 ( C18 first in pharmaceutical) . wen sample non polar use "NP" column like silica or CN Column. after that you can change the column in same packing to solve tailing, retention time, Resolution..... or any problem by change column length, particle size or carbon loud

### How do you insert 10000 rows to mysql in php?

The same way you insert 1 row, just 10,000 times. There are two choices, I'm going to assume you've already connected to mysql and you are prepared to run your query: 1. Transactional method: $query = "INSERT INTO foo (column) VALUES (row1), (row2), (row3) ... (row10000);"; mysql_query($query); This is ideal when it is imperative that all rows go into the database. Keep in mind that this method will tie up the database until the entire… Read More

### Why is the value of atmospheric pressure compared to mercury?

The common method to measure atmospheric pressure employs an inverted column submerged in a fluid to determine the level at which the column has to be raised to equalize the external atmospheric pressure and the internal column pressure. The height at which the fluid inside the column ceases to increase is correlated to atmospheric pressure. Due to mercury's high density, this level is on the order of inches (~30 inches of mercury at atmospheric pressure)… Read More

### What will be the answer if you have 1 square and in it 36 squares what is the number of squares?

You really should do your own homework - this is a question designed to make you analyse number patterns and devise a method to predict the answer that can be applied to grids of differing size. If we start with a square cut into a 3x3 grid, we can count the nine single (1x1) squares in the grid, the one 3x3 square, and then four 2x2* squares, making a total of 14. Try it out… Read More
