TFQA: Tools for Quantitative
TFQA Ordering Information
All TFQA programs run on PC's, running Windows 10, 7, and
XP. (They almost certainly run under Windows 8 and
Vista but have not been tested.) The few programs that
create full screen graphics do not run directly in Windows
7 or more recent versions, but there is a work-around that
works well but requires some setup (and administrator
privileges)--see Running TFQA
Graphics Programs. The programs are
network-compatible, and come with a 90 day money-back
guarantee. The most complete and up-to-date documentation
is on-line through this site here.
(An outdated 150 page manual is included with the download
as a PDF file formatted for easy printing.)
Orders. An order
is automatically generated when a payment is made from
this Web page (below). Orders may also be placed by
mail, email, or phone (please indicate whether an
individual or site license is desired).
Payment can be
made by credit card (through Paypal) or directly from a
Paypal account, in both cases through the "Buy Now"
button, below). All transactions are processed entirely by
Paypal. Let me know if you need a different form of
invoice than the one automatically emailed by Paypal.
Payment can also be made via check or money order in US
dollars, drawn on a US bank, and made out to TFQA.
Purchase orders should be made out to TFQA.
Individual and Site Licenses. The individual price licenses a single copy running on one machine at any one time. A user may install copies on, for example, home, laptop, and business computers, as long as the programs will not be used on more than one computer at the same time. A site license entitles the distribution of copies of the programs and documentation to all employees/students of a company, organization, or institution, again with home and laptop as well as business/school machines.
Download Instructions for the programs will ordinarily be emailed within a few hours of receipt of payment. The downloaded installation file (ca. 10MB) can be saved in case reinstallation is needed.
Complete Toolkit - $50. (individual), $150. (site
license). Updates for users who have purchased
earlier versions of TFQA) - $25 (individual) or $50
