Expected Frequencies in Goodness-of-Fit Tests

Expected Frequencies in Goodness-of-Fit Tests

A goodness-of-fit test is conducted to determine whether the observed frequency values are statistically similar to the frequencies expected for the dataset. Suppose the expected frequencies for a dataset are equal such as when predicting the frequency of any number appearing when casting a die. In that case, the expected frequency is the ratio of the total number of observations (n) to the number of categories (k).

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...

Functional Classification of Joints

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
Synarthrosis
An immobile...

Linear Approximation in Frequency Domain

Linear Approximation in Frequency Domain

Linear systems are characterized by two main properties: superposition and homogeneity. Superposition allows the response to multiple inputs to be the sum of the responses to each individual input. Homogeneity ensures that scaling an input by a scalar results in the response being scaled by the same scalar.
In contrast, nonlinear systems do not inherently possess these properties. However, for small deviations around an operating point, a nonlinear system can often be approximated as linear.

Frequency-Domain Interpretation of PD Control

Frequency-Domain Interpretation of PD Control

Proportional-Derivative (PD) controllers are widely used in fan control systems to improve stability and performance. A fan control system can be effectively represented using a Bode plot to illustrate the impact of a PD controller through its transfer function. The Bode plot visually conveys how PD control modifies the fan's response across various frequencies, providing a frequency domain interpretation of the controller's behavior.
The proportional control gain, combined with the system's...

Frequency-dependent Selection

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Background:

Mandarin Chinese is a tonal language where pitch contours significantly alter word meaning.
Existing models may not fully capture the complex dynamics of tonal variations.

Purpose of the Study:

To develop and apply a novel functional principal component (FPC) analysis model for quantifying pitch (fundamental frequency, F0) in Mandarin Chinese.
To identify and characterize the underlying tonal components within the language's pitch contours.
To discover potentially undocumented tonal features.

Main Methods:

Utilized functional principal component (FPC) analysis on preprocessed fundamental frequency (F0) curves from a Mandarin Chinese corpus.
Applied locally weighted least squares smoothing for F0 curve generation.
Employed penalized mixed-effect models to analyze FPC scores and build categorical prototypes.

Main Results:

Quantified the influence of each identified FPC on the original tonal content without prior shape assumptions.
Developed meaningful categorical prototypes that align with established Mandarin Chinese tonal characteristics.
Identified a previously undocumented sinusoidal tonal component within the language's pitch variations.

Conclusions:

The FPC analysis framework provides a robust method for modeling and understanding tonal dynamics in Mandarin Chinese.
The discovered sinusoidal component warrants further investigation for its phonetic and phonological significance.
