Shazam (econometrics software)

Shazam (econometrics software) is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Shazam (econometrics software) rather than just read about it. In short: Shazam is a comprehensive econometrics and statistics package for estimating, testing, simulating and forecasting many types of econometrics and statistical models. SHAZAM was originally created in 1977 by Kenneth White.

Key takeaways

Shazam (econometrics software) belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Shazam (econometrics software) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Shazam (econometrics software) from memory before moving on to harder problems.

Reference excerpt

Shazam is a comprehensive econometrics and statistics package for estimating, testing, simulating and forecasting many types of econometrics and statistical models. SHAZAM was originally created in 1977 by Kenneth White.

Data management All SHAZAM editions read and write both fixed and free format text formats using the READ and FORMAT statements. Data can be stored by observation (row) or by variable (column) with or without variable names. Through the supplied Windows Environment formats such as comma-separated values (CSV), Microsoft Excel (both XLS and XLSX) may also be read and written. SHAZAM Professional Edition contains comprehensive data import capabilities through its Data Connector and SQL editor allowing the import of machine data source such as tab, space or comma separated text formats, other file-based proprietary binary formats (including various Microsoft Excel formats) as well as Microsoft Access or any other LAN, WAN or internet data source for which the user has a driver on their system. In addition SHAZAM can import data from Database Management Systems (DBMS) and SHAZAM ships with drivers for most common data Database Management Systems.

Extensibility SHAZAM is extensible through the development of SHAZAM Procedures that can be included or reused in SHAZAM command files. Numerous SHAZAM Procedures have been written and are available from the SHAZAM Website or from many sites throughout the internet.

Editions SHAZAM is currently available in four editions. SHAZAM Command Line Edition (SHAZAMD and SHAZAMQ) are text user interface versions that allow batch processing. They operate in double and quad precisions. SHAZAM Standard Edition (SHAZAMW) adds a native Windows application that incorporates a multiple document interface (MDI) interface including command, data, matrix, graph editors and a Workspace viewer along with integrated online help, samples and examples. SHAZAM Professional Edition (SHAZAMP) adds menu and wizard driven facilities for executing SHAZAM techniques, a data connector with SQL editor as well as an integrated debugger.

Worked examples

Example 1 — a first encounter with Shazam (econometrics software)

Start with the simplest possible case. Write down what Shazam (econometrics software) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Shazam (econometrics software) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Shazam (econometrics software) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Shazam (econometrics software)

In research: Shazam (econometrics software) appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Shazam (econometrics software) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Shazam (econometrics software) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Econometrics software, Proprietary software, Regression and curve fitting software, so understanding it makes those chapters shorter.
In everyday life: Look for Shazam (econometrics software) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
