Scan Statistics and Applications is a comprehensive, edited survey that brings together the work of leading authorities to present the most current advances in theory and methodology for this new area of statistical research and application. The chapters contain broad coverage of theory and new analytical and computational methods and techniques in four categories: introductory survey, discrete scan statistics, continuous scan statistics, and applications.
The subject can be quite exciting to probabilists, researchers and graduate students learning about these techniques in relation to scan statistics as a central point. The chapters are well written in a review style, discussing the main issues of scan statistics in a particular topic, and presenting the motivation and the main results, mostly without proving them. Proofs can be found in the related original papers. However, some hints and discussions are given on how to derive certain results.

I enjoyed every chapter as well as the whole book. It would be interesting to have an update of the book in a few years to appreciate the developments and new results on scan statistics.
The present edition of the book is good value for money. Finally, their tech providers are speaking their specific business language.
But with verticals, it is about understanding the software, all of those specific-use applications that pertain to the industry in question. That will earn you true vertical street cred. Many cloud-based ISVs are developing discrete applications tied to specific industries. These are often small firms lacking a largescale sales operation and eager to grow.
As a result, many are beginning to experiment with indirect channel partners to grow their footprint and penetrate various customers segments. It is most likely this group that has made a concerted effort to make one or more vertical industries a strategic focus and a significant source of revenue. This is not the same as becoming an expert in the applications and business processes that an individual vertical such as retail requires. That level of expertise is what truly comprises vertical industry focus and is what many ISVs, vendors and customers are seeking in their channel partners.
It needs noting that vertical specialization is not the simplest path to pursue successfully. Breaking into a specific industry, mastering the vernacular along with niche applications and processes takes time and investment. Technical acumen is the comfort zone for the channel after all. The enormity of the industry is a function of many of the trends discussed in this report. Economies, jobs, and personal lives are becoming more digital, more connected, and increasingly, more automated.
Waves of innovation build over time, powering the technology growth engine that appears to be on the cusp of another major leap forward. In the U. Despite the size of the U. Spending is often correlated with factors such as population, GDP, and market maturity. Among global regions, Asia-Pacific is the largest, accounting for approximately one of every three technology dollars spent worldwide. Many APEC countries enjoy the twofold effect of closing the gap in categories such as IT infrastructure, software, and services, along with leadership positions in emerging areas such as robotics.
If these patterns hold, APEC will continue to grow its share of the global technology pie at the expense of slower growing markets. The bulk of technology spending stems from purchases made by corporate or government entities. A smaller portion comes from household spending, including home-based businesses. With the blurring of work and personal life, especially in the small business space, along with the shadow IT phenomenon, it can be difficult to precisely classify certain types of technology purchases as being solely business or solely consumer.
CompTIA projects the global information technology industry will grow at a rate of 4. The optimistic upside forecast is in the 6. This is a broader forecast range than what has been seen in the past couple of years, meaning industry executives see the possibility of more extreme divergence in growth scenarios.

Conversely, a global slowdown in demand, or any slowdown in the adoption of emerging technologies could dampen growth enough to push it towards the 1. Growth expectations for the U. As the largest tech market in the world, U. CompTIA uses a consensus forecasting approach.
The results attempt a best-fit forecast that reflects the sentiment of industry executives. Other factors that influence revenue growth projections include currency effects, pricing, and product mix. The tech space is somewhat unique in that prices tend to fall, which may result in large numbers of units shipped, but modest revenue growth.
In the year ahead, the product mix will be an especially important factor, as the high growth rates of emerging categories are expected to more than offset the slow growth mature categories. There are a number of taxonomies for depicting the information technology space. Using the conventional approach, the industry market can be categorized into five top level buckets. The allocation of spending will vary from country to country based on a number of factors. In the mature U. This paves the way for investments in the software and services that sit on top of this foundation.
As noted in trend 1 above, advances in cloud computing, edge, 5G, and other infrastructure technologies, will usher in the next wave of services and software. Tech services and software account for nearly half of spending in the U. Countries that are not quite as far along in these areas tend to allocate more spending to traditional hardware and telecom services. Building out infrastructure and developing a broad-based digital workforce does not happen overnight.
Scenarios do exist, however, whereby those without legacy infrastructure — and the friction that often comes with transitioning from old to new, allows for an easier path to jump directly to the latest generation of technologies. Beyond growth projections, business sentiment is a useful gauge of how industry executives feel about current and future conditions.
Despite being off its high, heading into , business confidence among IT industry executives remains well above the long-term average for the index.
The data suggest IT industry business confidence runs counter to other industry sector or consumer indices, many of which dipped during late and early This comes as no surprise given the unease stemming from rising debt levels, stock market volatility, international tension, the record-setting government shutdown, Brexit, and any number of other factors. Despite the recent turmoil, international trade remains the backbone of the global technology market. On the production front, a single smartphone may source components from hundreds of suppliers spanning 20 or more countries.
Supply chains have never been more global and interconnected. On the consumption front, buyers gravitate toward the best experience, which often encompasses hardware, software, and service ecosystems, wherever they may reside. While convergence continues to be a powerful force in driving users toward similar experiences, the counter weight is the desire for personalization and localization, especially among the always-influential youth market.
As such, many countries eagerly import and export technology products and services from trade partners, enjoying the benefits of consumption and economic value creation. For the most recent year of available data, U. For many tech bellwethers, exports account for an even higher percentage of sales, with some generating more than half of their revenue from overseas customers. There may not be a next big thing, but there is one very big thing that is as old as IT itself.

Cybersecurity continues to rise in importance as business and daily life are increasingly digitized. Many businesses are increasing their security investments or elevating their security focus, but these actions often follow a defensive approach that utilizes technology tools such as firewalls and antivirus. More and more, firms will realize that they must be proactive in probing for weaknesses or detecting possible breaches. This will involve new skills such as penetration testing, vulnerability assessment, and security analytics.
Beyond the technical aspects, organizations will also begin building business processes that enhance security, and they will implement end user training to mitigate human error.

There is no doubt that companies are taking security more seriously, but now they must realize that modern security demands a different mentality rather than just more of the same. Analysis of the tech workforce begins with an important distinction. Using the classic Venn diagram as a reference point, the tech workforce consists of two separate components, with an area of overlap.
