Software Development: Testing

This presentation discusses the role and purpose of testing in the systems/Software Development Life Cycle. We examine the consequences of the 'cost curve' on defect removal and how agile methods can reduce its effects. We concentrate on Black Box Testing and use Equivalence Partitioning and Boundary Value Analysis to construct the smallest number of test cases, test scenarios necessary for a test plan.

Measuring and testing for the systemically important financial institutions

This paper analyzes the measure of systemic importance ∆CoV aR proposed by Adrian and Brunnermeier (2009, 2010) within the context of a similar class of risk measures used in the risk management literature. In addition, we develop a series of testing procedures, based on ∆CoV aR, to identify and rank the systemically important institutions. We stress the importance of statistical testing in interpreting the measure of systemic importance. An empirical application illustrates the testing procedures, using equity data for three European banks.

Statistical inference for testing Gini coefficients: an application for Colombia

This paper uses Colombian household survey data collected over the period 1984-2005 to estimate Gini coe¢ cients along with their corresponding standard errors. We Önd a statistically signiÖcant increase in wage income inequality following the adoption of the liberalisation measures of the early 1990s, and mixed evidence during the recovery years that followed the economic recession of the late 1990s. We also Önd that in several cases the observed di§erences in the Gini coe¢ cients across cities have not been statistically signiÖcant.

Testing for Stock Market Integration in a Developing Economy: Colombia

This paper examines the linkage between two parallel stock exchanges trading the same shares in Colombia, namely the Bogotá Stock Exchange and the Medellín Stock Exchange. We provide empirical evidence to support the hypothesis that these two markets can be best described as fully integrated over a period of almost four decades, which is consistent with the view that arbitrage opportunities are only possible in the short but not in the long run. In addition, we find evide

Testing the law of one price in food markets: evidence for Colombia using disaggregated data

This paper applies stationarity tests to examine evidence of market integration for a relatively large sample of food products in Colombia. We Önd little support for market integration when using the univariate KPSS tests for stationarity. However, within a panel context and after allowing for cross sectional dependence, the Hadri tests provide much more evidence supporting the view that food markets are integrated or, in other words, that the law of one price holds for most products.

Genetic testing with primary prevention and moral hazard

We develop a model where a free genetic test reveals whether the individual tested has a low or high probability of developing a disease. A costly prevention effort allows high-risk agents to decrease the probability of developing the disease. Agents are not obliged to take the test, but must disclose its results to insurers. Insurers offer separating contracts which take into account the individual risk, so that taking the test is associated to a discrimination risk. We study the individual decisions to take the test and to undertake the prevention effort as a function of the effort cost and of its e¢ ciency. We obtain that, if effort is observable by insurers, agents undertake the test only if the effort cost is neither too large nor too low. If the effort cost is not observable by insurers, they face a moral hazard problem which induces them to under-provide insurance. We obtain the counterintuitive result that moral hazard increases the value of the test if the effort cost is low enough. Also, agents may perform the test for lower levels of prevention e¢ ciency when effort is not observable

A Communicative Approach to Testing : II parte.

Se recogen una serie de actividades en inglés a modo de pruebas de evaluación sobre contenidos interdisciplinares relativos al medio ambiente. El objetivo es relacionar la lengua inglesa con otras asignaturas, potenciando al mismo tiempo la capacidad lingüístico-comunicativa de los alumnos en otro idioma (investigación, análisis de datos, deducciones lógicas, argumentación, etc). El material utilizado son artículos de periódicos y revistas, fragmentos de programas de televisión, cómics, etc y va dirigido a jóvenes del nuevo bachillerato..

Se han incorporado y ampliado capítulos respecto de la edición anterior con distintos tipos de tests para jóvenes estudiantes y con las llamadas pruebas técnicas. También, cuenta con apéndices nuevos sobre análisis estadístico de test de datos y sobre los bancos de ítems.

A Communicative Approach to Testing. 'Una aproximación comunicativa a la evaluación'.

El presente documento realiza un estudio sobre los distintos criterios y técnicas de evaluación que se pueden aplicar al conocimiento de la asignatura de lengua inglesa por parte de los alumnos. Se valorará la participación de éstos en conversaciones breves, la redacción de textos sencillos con una estructura lógica, el establecimiento de comparaciones para establecer semejanzas y diferencias entre objetos, personas, etc., la capacidad para comprender textos sencillos... Los contenidos están dirigidos a alumnos de tercero y cuarto curso de la Educación Secundaria Obligatoria.
