We are receiving a lot of questions about relevant analyses in the Analyse-it Method Validation edition to help in evaluating new diagnostic tests in the fight against COVID-19. Below are some quick links that will help, but contact us if you have questions - we are working as normal.

Our focus at Analyse-it has always been on the development and improvement of our software. While we provide extensive help, tutorials, and technical support for Analyse-it, one area we do not cover is training and consultancy. As many of you will know we are based in England in the United Kingdom, and providing training and consultancy is often done better locally, in-person.
Instead we partner with experts who can provide training and consultancy in various disciplines, in local language, and geographically near (or at least nearer) to our customers. You can always find a list of current consultant and training partners at https://analyse-it.com/support/training
One of the experts we have had a long relationship with is Dr. Thomas Keller. Dr Keller is an independent statistician and has run ACOMED statistik for 15 years. One his many areas of expertise is the planning and evaluation of experiments for method validation and he has been involved in international working groups (IFCC, CLSI) in the fields of clinical chemistry and laboratory medicine. Dr. Keller was actually a customer and started to provide training in Analyse-it shortly after. His reputation is second to none in the industry and he has provided consultancy and training to many companies using Analyse-it. See an example of a course on Method Validation according to CLSI guidelines offered by Dr. Keller. He also provides WebEx and telephone consultations for anything from simple questions to full courses for individuals and small groups.
Dr. Keller is providing a training course in April on how to use Analyse-it in bio-statistical analysis. The course will be in Germany, in Leipzig, and details are below. If you would like to attend, would like to consult with Dr. Keller, or maybe even arrange a similar course for your colleagues, please contact Dr. Keller at https://analyse-it.com/support/training#drThomasKeller

3rd April 2019, 9am to 5pm

The evaluation of data from clinical laboratories and biomedical research requires a sound statistical basis. In addition to the generation of research results, statistical methods also play a central role in quality assurance and method validation. A suitable software for this is the Excel-Add-On Analyse-It®, which provides basic statistical evaluations regarding estimation and testing as well as method validation. The software is based on the methodology described in the CLSI (Clinical Laboratory Standard Institute).
The seminar will introduce basic methods of bio-statistics. Data from method validation experiments will mainly be used as examples. The aim of the seminar is to introduce scientific staff and laboratory assistants to basic statistical approaches and at the same time to apply and deepen this knowledge in exercises.
The event is aimed at scientists and laboratory assistants from biomedical research as well as clinical laboratories and comparable institutions who use Microsoft Excel and, if applicable, Analyse-It® for their analyses or are planning to do so.
The workshop will be provided in German language only. In the seminar exercises with the statistics software Analyse-It® will form an important part. Participants should bring their own laptop with MS Excel installed. In addition, a temporary license for the Analyse-It® software will be provided in advance.

Today marks the 20th birthday of Analyse-it.
It was December 1997 when we shipped the first disks containing Analyse-it to paying customers. In some ways it seems just like yesterday, but in other respects software development and Analyse-it has come so far in those 20-years.
As many of you know Analyse-it wasn’t our first foray into developing statistical software. My co-founder in Analyse-it, Simon Huntington, had previously developed . Astute was the first statistical add-in for Microsoft Excel, initially released in 1992 for Excel 4.0, and released a few months before Microsoft’s Data Analysis Toolpak which appeared in Excel 5.0.
We are delighted to announce the addition of the Analyse-it Quality Control and Improvement Edition to the range of Analyse-it products.
The new edition includes the most impressive statistical process control (SPC) charts available in any Excel statistical software package, including Shewhart, Levey-Jennings, CUSUM, and EWMA charts. Process capability statistics and plots help you ensure a process is able to meet specifications. And Pareto plots help you identify the quality-related problems that need the most attention and let you monitor efforts to reduce them.
A critical feature of any analytical and statistical software is accuracy. You are making decisions based on the statistics obtained and you need to know you can rely on them.
We have documented our previously, but another good benchmark to test statistical software against is the NIST StRD. The Statistical Engineering and Mathematical and Computational Sciences Divisions of NIST’s Information Technology Laboratory developed datasets with certified values for a variety of statistical methods against which statistical software packages can be benchmarked. The certified values are computed using ultra-high precision floating point arithmetic and are accurate to 15 significant digits.
Probably the greatest concern when using statistical software is reliability. Is the software producing accurate, numerically correct results that have been validated?
It’s a very important question. Many of you work in FDA and regulated environments where the penalties for mistakes are very high. And those of you outside such environments are still making important business and research decisions using Analyse-it. It’s therefore imperative that the software you depend upon is developed to a professional standard, thoroughly tested and validated.
Leeds, England (PRWEB) October 03, 2012 -- Analyse-it Software, Ltd. today announced a major new release of their popular , Analyse-it®. With support for Excel 2007, 2010 and the forthcoming Excel 2013, Analyse-it transforms Microsoft Excel into a cost-effective powerful statistical analysis and data visualization package. Statistics and plots are included for exploring and describing data, estimating parameters, testing hypotheses, uncovering relationships and fitting models.
The British government recently announced a 2.5% reduction in VAT (sales tax) on goods purchased from the United Kingdom (see ). UK VAT was previously 17.5%, but from the 1st December 2008 until the end of 2009 it has been reduced to 15%.
Like many businesses, last Monday, we implemented the change.
Customers in the United Kingdom who aren’t VAT exempt, and those of you in Europe who are not VAT registered and must pay VAT, will now pay only 15% VAT.
We’re pleased to announce that from today we can accept payment in EUROs. You can now see prices for Analyse-it in EUROs, as well as British Pounds sterling, and US dollars (for customers in the USA & Canada).
The EURO is now the primary currency in Europe and many of our customers have asked us to accept EUROs. We can accept payment in EUROs by VISA, MasterCard or AMEX credit card, or by cheque or wire-transfer.
Depending on where you’re located, the way we spell “Analyse-it” may intrigue you. We chose the name in 1997 as it sounded active, a direction to analyse it! – similar to many product names of the time.
The name has served us well and hints as to what our business and product offers.
At the time we didn’t think such a simple name would cause so many headaches. Before you wonder, Analyse-it doesn’t mean anything offensive in other languages, but it can be spelt different ways:
Thanks for stopping-by to read the inaugural post to the Analyse-it blog.
We’ve launched the to keep you up-to-date on what’s new at Analyse-it, what we’re working on, and to notify you when updates and new products are released. We’ll also blog about using Analyse-it, statistical analysis, and interpretation.
The best part about the blog is it’s a conversation -- a conversation between you, our visitors and customers, and us. After reading a post you can add your thoughts, suggestions, and comments. We’ll reply when necessary or other visitors can post their opinions to ignite the debate. Click the links at the end of each post to read comments or add your own.
