In Microsoft Excel, the LINEST function is easy to use. However, you have to master the array function concept. When this array function is entered within a single spreadsheet, the cell produces results filling the few cells. Here are steps to help you through the linear curve fitting process.

• Key-in the data within two columns, one is for the y variables and the other is for the x variables.
• Choose the area holding the array formula output.
• Click the formula bar, which is located at the top of the spreadsheet. Now, press the wizard button function. This is within the formula bar that is labeled as fx. Two scroll box will appear; LINEST is in the right and STATISTICAL is located on the left scroll box. Click the NEXT> button. There you will see through the spreadsheet, which contains the y values through dragging inside the original spreadsheet with the mouse. Click the dialog box which contains ‘known_x’s’ then choose the cells that contain the x values. Type the keyword ‘TRUE’ within its last two dialog boxes. The first TRUE points out the line that to be within the form of ‘y=mx+b’ having the intercept of non-zero. The other specifies the error estimates, which have to be listed.

The Emerging World of Telecom Expense Management

At one point in time, businesses essentially had no mobile work forces. A couple of decade or so ago, however, the emergence of the cell phone gradually led to more people chatting in the service of their employer. That situation grew as BlackBerries, smartphones and tablets proliferated.

That’s a good thing, of course. Work is more efficient and productive as employees carry it out from trains, (to some extent) planes and automobiles.

But there is a huge challenge: Companies either give out devices — a very expensive proposition — or allow employees to use their own and T&E parts of their bills. The former is fading as an approach. The latter, unless extremely well managed, leads to an almost incredible amount of waste.

Companies need to work out sophisticated policies in concert with carriers to ensure than they are getting the best deals possible. Negotiating with carriers for employee plans lets them pool minutes and lets the same plan support the more office-bound workers and those who travel a lot. This means that there is less waste as the company borrows from Peter to pay Paul, so to speak. In addition, it should be noted that data pooling is coming.

There are many other reasons that companies must standardize as much as possible. A clear set of policies will enable the organization to know who is using what type of device and the level of security that it has. Thus, an executive using a smartphone without adequate security is a big problem, if he or she is working on sensitive data while on the road. TEM can help ferret out such problems — which can end up saving the organization regulatory and/or legal problems.

How to Compute Intercept in Microsoft Excel Through the INTERCEPT Function

Aside from using it as a database, it is also an excellent tool for calculation of mathematical problems. Because of the different functions of the program, certain mathematical problems can be computed easily. One of the functions that are usually utilized in Excel is the INTERCEPT function. By reading the article, Excel programmers will be acquainted to one of the essential functions of Microsoft Excel.

INTERCEPT Function Overview

The function is used to compute the point where a certain line will meet the y-axis with the use of the given values of x and y. The point of intersection is in accordance with the well fitted regression line that is plotted using the identified value of x and y. The function is recommended to be used when determining the value of the dependent variable when that the value of independent variable is equal to zero.

Correct Syntax to Use

In order to employ the function correctly, the right formula to use is:

=INTERCEPT(known_y’s, known_x’s)

Where:

• Known_y’s – is the set of dependent data or information
• Known_x’s – the set of independent data or information

Important Details to Remember

Since Excel is a Microsoft program that function based on formula, there are certain things that need to be remembered in order to use the program efficiently and they are:

• The arguments must be names, numbers, arrays or cell reference containing numbers.
• Once the reference or the range arguments contain logical values, text or blank cells, then the values are all ignored. But, the cell that contains a zero value is included in the computation.
• Once the value of known_y’s and known_x’s are diverse numbers of data points, the answer of the function would be #N/A! error.

INTERCEPT Function Example

For a better understanding of the function, take a look at the given example below and try using the INTERCEPT function.

Find for the intercept if the given value for y is 5, 6, 8, 2 and 3. On the other hand the given value for x is 10, 3, 7, 5 and 4.

To compute for the intercept using Microsoft Excel, below are the steps to be followed:
