"WitrynaThere are more advanced representations such as log area ratios (LAR), line spectral pairs (LSP) decomposition and reflection coefficients. Of these, especially LSP decomposition has gained popularity since it ensures the stability of the predictor, and spectral errors are local for small coefficient deviations.

WitrynaThe LPC derived log area ratio coefficients are defined as gi=log (1-ki/1+ki) where ki comes from the Durbin's iterative method. I am wondering whether gi/ki (PARCOR coefficients) physically correponds to which side of the vocal tract. Suppose the LPC is of p order from 1 to p. Thanks in advance.

Witryna8 wrz 2024 · This β is the logs odds ratio between the two treatments for patients coming from the same hospital. Now, if you had analyzed the same data with a generalized estimating equations (GEE) approach, then you would get coefficients with a marginal interpretation. WitrynaIn telecommunicationsand transmission linetheory, the reflection coefficient is the ratioof the complex amplitudeof the reflected wave to that of the incident wave. The voltage and current at any point along a transmission line can always be resolved into forward and reflected traveling waves given a specified reference impedance Z0.
