This page provides prices for updating or upgrading existing licenses of RATS for Windows or Macintosh to the current release. Please see UNIX Updates for update prices for UNIX/Linux.
If you would like to receive updates automatically as soon as they are released, you may want to consider purchasing an Update Subscription. Update Subscriptions also provide organizations with an efficient and economical way to budget update purchases.
To order by mail or fax, you can download and print out the RATS 8 Update Order Form or the Estima Order Form. The latter also includes prices for the CATS cointegration analysis procedures and our database and textbook products.
Please contact us at sales@estima.com for quotes on updating multiple copies, network or cluster licenses, or if you have any other questions.
Please Note: If you are a bit bewildered by all the combinations shown below, you may want to see our On-line Order Form. Even if you don't plan to order via the Web, you can use the form to compute the correct price, including shipping costs and sales tax where applicable.
