Determination of Expected Frequency

Determination of Expected Frequency

Suppose one wants to test independence between the two variables of a contingency table. The values in the table constitute the observed frequencies of the dataset. But how does one determine the expected frequency of the dataset? One of the important assumptions is that the two variables are independent, which means the variables do not influence each other. For independent variables, the statistical probability of any event involving both variables is calculated by multiplying the individual...

Background:

Stimulus-frequency otoacoustic emissions (SFOAEs) offer a noninvasive method for evaluating cochlear function.
Limited research exists on the predictive value of SFOAEs for hearing capabilities.

Purpose of the Study:

To develop and validate an objective assessment system based on SFOAEs for predicting hearing thresholds and identifying hearing loss.
To evaluate the performance of routine and fast testing modules for threshold prediction and a screening module for hearing status identification.

Main Methods:

Trained predictive models using SFOAE data from 245 normal-hearing ears and 839 ears with sensorineural hearing loss.
Developed three modules: routine test, fast test (for threshold prediction), and hearing screening.
Validated model performance using cross-validation and independent unknown datasets.

Main Results:

Routine and fast test modules demonstrated similar performance in predicting hearing thresholds from 0.5 to 8 kHz (mean absolute errors: 7.06-11.61 dB and 7.40-12.60 dB, respectively).
The fast module offered reduced testing time compared to the routine module.
The hearing screening module achieved high accuracy (88.4-95.9%) and a low false-negative rate (2.9-7.0%) across 0.5-8 kHz, with a large area under the ROC curve (0.912-0.985).

Conclusions:

The developed SFOAE-based system shows potential for objective hearing assessment.
The routine and fast modules are viable for hearing threshold prediction, though improvement is needed for ears with hearing loss.
The hearing screening module demonstrates significant promise as a clinical tool for identifying hearing loss.
