      <content:encoded><![CDATA[I recently created an add-in to create a variance/covariance matrix for Excel 2007. If you follow that link, you will be able to read about the add-in and how to use it. The purpose of this post is to announce that I have created the same add-in for prior versions of Excel. 
Note that both versions of the add-in are now updated so that they will calculate either a population or sample variance/covariance matrix. This version of the add-in works in Excel 2003. It should work fine in other recent versions, though I haven&rsquo;t tested it in anything prior to 2003. It only differs from the Excel 2007 version in that it adds a Var/Cov Matrix menu item to the Data menu.<br/>

      <content:encoded><![CDATA[Excel doesn&rsquo;t always do everything that you might want, or it doesn&rsquo;t do it in a way that is sufficient for your needs. That&rsquo;s why we have VBA and add-ins. I finally decided to do something about one problem that has been bothering me for years. The variance/covariance matrix is very important in finance. In particular, it is needed to calculate the standard deviation (volatility) of a portfolio, and is used to calculate the beta of an asset. It also has numerous uses in other fields. For this reason, Excel provides the Covar() function and also the Covariance tool in the Analysis ToolPak add-in. While Excel&rsquo;s built-in tools are perfectly functional, they don&rsquo;t always work in exactly the way that I would like. In particular, the Covariance tool doesn&rsquo;t...<br/>

      <content:encoded><![CDATA[I’m knee-deep into work on the 5th edition of Financial Analysis with Microsoft Excel, but I feel the need to make this post while I’m thinking about this stuff. I have finally figured out how to create high quality screenshots of various Excel dialog boxes and other components. This is something that I’ve been trying to get to work for a long time, but I had to rely on the artists at my publisher to spruce up screenshots in the past. I’m no artist, so I didn’t figure this out on my own. I got the instructions from the graphicPUSH blog, and I did some experimenting of my own. I’ll share the steps that I’m using in this post. If you have better ideas, I’d love to hear about them in the comments. At the end of the post is a link to a PDF file that can be downloaded to see the results in a...<br/>

If you are like me, you may need to run both Office 2003 and Office 2007, and it is a real time saver to be able to do that without booting up another PC. The purpose of this post is how to run both versions on a single PC.<br/>

      <title>The NPV Function Doesn’t Calculate Net Present Value</title>

      <content:encoded><![CDATA[One of the things that has always driven me nuts (because I have to repeatedly explain it in class) is that the NPV function in spreadsheets doesn't really calculate NPV. Instead, despite the word "net," the NPV function is really just a present value of uneven cash flow function. It has always been this way, so I've learned to live with it. I suspect that this goes all the way back to Visicalc (which you can download and run in a DOS window).

Net present value is defined as the present value of the expected future cash flows less the initial cost of the investment. "Net" always means that something has been subtracted, so it is puzzling that spreadsheets have done this (there are actually a number of crazy errors that have been propagated over the years to maintain compatibility).

      <content:encoded><![CDATA[A couple of months ago, I created my first screencast video using Camtasia Studio from TechSmith. This is a great tool, but I need to work a bit on my video creation skills. Today, I posted the video on YouTube, and I hope that people will find it useful. The video shows how to create a step function chart in Excel.<br/>

      <title>On Arrays and Accumulated Depreciation</title>

      <content:encoded><![CDATA[What could be easier, or more common, than calculating accumulated depreciation? Generally, in your spreadsheets you probably have each years' depreciation expense listed in its own cell and all you do is add them up. Nothing wrong with that, but there is another way.

I like to read the forums over at AnandTech and help out whenever I can. Not long ago, a user asked about calculating accumulated depreciation using the DDB (double-declining balance) function. He needed to calculate the accumulated depreciation to date for an asset so that the book value could be calculated. My solution was quite simple, but it makes use of arrays and I don't think most Excel users are aware of this functionality.<br/>
