Evaluation of prescriptive fitting.
The purpose of this study was to determine the minimum tolerance needed when choosing a manufacturer who custom-built analog circuitry for all-in-the-ear hearing aids to match a popular prescriptive amplification formula. Given the tolerance, a second purpose was to evaluate fitting success by calculating the differences in prescribed versus preferred gain and pre- versus postfitting perceived ...
متن کاملSimple fitting of subject-specific curves for longitudinal data.
We present a simple semiparametric model for fitting subject-specific curves for longitudinal data. Individual curves are modelled as penalized splines with random coefficients. This model has a mixed model representation, and it is easily implemented in standard statistical software. We conduct an analysis of the long-term effect of radiation therapy on the height of children suffering from ac...
متن کاملFitting Multivariage Normal Finite Mixtures Subject to Structural Equation Modeling
This paper is about fitting multivariate normal mixture distributions subject to structural equation modeling. The general model comprises common factor and structural regression models. The introduction of covariance and mean structure models reduces the number of parameters to be estimated in fitting the mixture and enables one to investigate a variety of substantive hypotheses concerning the...
متن کاملFitting a Finite Mixture Distribution to a Variable Subject to Heteroscedastic Measurement Error
We consider the case where a latent variable X cannot be observed directly and instead a variable W X U with an heteroscedastic measurement error U is observed It is assumed that the distribution of the true variable X is a mixture of normals and a type of the EM algorithm is applied to nd approxi mate ML estimates of the distribution parameters of X
متن کامل[The evaluation for hearing aids fitting by using TR60 (a new system of hearing aids fitting)].
We have studied 131 patients (over 12 y/o) for hearing aids evaluation by the Noise Impulse Hearing Test using the fitting system TR 60 and have compared the test results with the subjective estimation of the patients wearing hearing aids. The judgement for selection of hearing aids by TR 60 is made by measuring most comfortable level (MCL) on the condition of wearing hearing aids, using narrow...
