[June 12,2013] This week, we present our fourth installment in our ongoing series of selected case studies. As with the other installments, we use real financial data to construct models with the help of NumXLi
In this case study, we examine closely the highway retail price ($/Gallon) for "No.2 Ultra Low Sulfur (0-15 ppm) Diesel" in the EIAi nine (9) PADD regions. We carry on principal component analysis in an attempt to find a minimal subset of the principal components that capture (or explains) the variation (spreads) in prices across different regions with a minimal loss of information.
Making sense of Diesel Prices
[June 5, 2013] This is our third installment in an ongoing series of demonstrating select case studies. We'll use real financial data to construct models with the help of NumXLi.
In this paper, we discuss the capital asset pricing model (CAPMi) underlying assumptions, define systematic and idiosyncratic risk, and outline their implication on the covariance among assets. Afterward, using a simple regression model, we compute the CAPM sensitivity factor (beta) for two different tech stocks: Microsoft and IBM. This paper will pave the way for more advanced factor modeling techniques in upcoming tutorials.
Calculating CAPM Beta
May 20, 2013 With great reluctance, Spider will be increasing the price of a NumXLi license with the release of NumXL 1.60 (Apache)
As a token of our appreciation to current customers, we decided to exclude them from this price change. We deeply appreciate your continued support. Thank you for being great users.
For a complete list of the changes that will take effect with the release of Apache, please refer to the NumXL release notes.

May 20, 2013: We are excited to announce the release of the latest version of NumXLi 1.60 (APACHE).
In addition to many fixes, the new version now thoroughly supports principal component analysis (PCA) and regression analysis and modeling. This will greatly streamline the process of creating robust regression models for everyday use without missing a beat. This version also include multicollinearity and regression stability tests.
For a complete list of the changes, please refer to the NumXL release notes.

The latest update to the NumXL software you’ve been waiting for is almost here. But we first need your input.
In addition to many bug fixes, the new beta version includes extra functions every analyst should have access to.
With NumXL 1.60, you will be able to perform regression analysis, principal component analysis, a multi-collinearity test and a Chow test for regression stability through a simple, user-friendly interface.
We encourage our customers to join the beta program by contacting our beta support team at beta@numxl.com for information about the program and instructions for downloading NumXL-beta.
