Design and analysis of discrete choice experiments for models with response time

2013

Settore SECS-S/02 - Statistica Per La Ricerca Sperimentale E TecnologicaA sector of conjoint analysis (experimental design in marketing research) is made of the so called choice experiments. In choice experiments respondents undergo a questionnaire which is nowadays mostly submitted through the internet. The questionnaire proposes to the respondent a sequence of choice sets each one including two or more profiles being a profile a specific combination of attribute levels. The respondent selects the preferred profile for each choice set. Responses given by a sample of respondents are analysed through suitable methods aimed to eventually find the best combination of attribute levels. One method of analysis adopts the Multinomial Logit (MLN) model. In this article the authors show the results of the MLN analysis compared with another model of analysis which uses an additional response which can be easily recorded by electronically submitted questionnaires. In practice modern survey platforms like “Qualtrics” (the one used for this work) can record the so called “response latency” i.e. the time taken by the respondent to make the choice and select the most preferred profile in the choice set. Thanks to a response latency model further refined in this work it is possible to deduce the relative weight of importance of the profiles for each choice set and respondent. This type of response can be used in place of the dichotomous choice variable in the MLN model. The two models and methods of analysis are deeply compared and it is critically discussed when it is better to use one or the other method. As a result a more reliable estimate of the optimal profile comes up implying lower risks for new investments and marketing decisions.

Prioritisation of alternatives with analytical hierarchy process plus response latency and web surveys

2014

This paper introduces a new method that combines the well-known analytical hierarchy process (AHP) with a response latency metric. The response latency is the time taken by respondents to make choices over pairwise comparisons. The analytical calculation of relative importance weights of the alternatives is made by using a response latency model previously validated in several case studies. This combination aims to overcome some drawbacks of the traditional AHP related to the use of a rating scale (the so-called Saaty scale), and it is a natural way to involve response latency in established decisionmaking methods. This new method can be profitably adopted in web surveys where it is easy to…

La soddisfazione degli utenti interni delle aziende ospedaliere: considerazioni su uno strumento di misura

2003

The paper proposes the application of two different methodologies, based on the Traditional Test Theory (TTT) and on the Modern Test Theory (IRT), to select the items of a questionnaire administered in the year 2000 to the personnel of the Hospital Firm “Careggi” in Florence, in order to analyse the satisfaction of “internal consumers”. Such methodologies provide very different results, depending on the assumptions of the different models used.

Analysis of stamping performances of dual phase steels: A multi-objective approach to reduce springback and thinning failure

2009

The industrial interest on light weight components has contributed in the last years to a significant research effort on new materials able to guarantee high mechanical properties, good formability and reasonable costs together with reduced weights when compared to traditional mild steels. Among such materials advanced high strength steels (AHSS) such as transformations induced plasticity (TRIP) and dual phase (DP), and light weight alloys proved their usefulness in stamping of automotive components. As AHSS are concerned, one of the main drawbacks is related to springback occurrence. Many aspects have to be taken into account when springback reduction is investigated: material behavior iss…

Exploring the effects of gender, age, income and employment status on consumer response to mobile advertising campaigns

2008

PurposeThe purpose of this paper is to examine the effects gender, age, income and employment status on consumer response to short message service (SMS)‐oriented direct‐response requests or a call‐to‐action tactic in a television advertisement or program, consumer's participation in SMS sweepstakes or other competitions, and consumer uptake of mobile services such as ringtones, logos, screensavers and wallpapers ordered by SMS message.Design/methodology/approachThe data used in this study were collected via an online survey. A total of 4,062 consumers responded to this survey. Cross‐tabulation and binary logistic regression were used to examine the associations between the explanatory varia…

Algorithm To Calculate Heart Rate By Removing Touch Errors And Algorithm Analysis

2018

Heart rate is one of the important physiological parameter to measure the stability of the health. This study shows analysis of a proposed algorithm to calculate heart rate with miss touch errors to make it more efficient. Android Smart phone with good quality camera has come to reach of common people and has become one of the most necessary and powerful device for today and of course, for future generation. We can use its powerful features to solve or assess heart state monitoring through capturing necessary data in the form of image. Mobile camera has a photo emitting diode and a photo detector. Light source illuminates the tissue and photo-detector calculates the small intensity variatio…

On the performance of multi-GPU-based expert systems for acoustic localization involving massive microphone arrays

2015

Sound source localization is an important topic in expert systems involving microphone arrays, such as automatic camera steering systems, human-machine interaction, video gaming or audio surveillance. The Steered Response Power with Phase Transform (SRP-PHAT) algorithm is a well-known approach for sound source localization due to its robust performance in noisy and reverberant environments. This algorithm analyzes the sound power captured by an acoustic beamformer on a defined spatial grid, estimating the source location as the point that maximizes the output power. Since localization accuracy can be improved by using high-resolution spatial grids and a high number of microphones, accurate …
