Caviar

Quantitative assessment of 12-lead ECG synthesis using CAVIAR.

The objective of this study is to assess the performance of patient-specific segment-specific (PSSS) synthesis in QRST complexes using CAVIAR, a new method of the serial comparison for electrocardiograms and vectorcardiograms. A collection of 250 multi-lead recordings from the Common Standards for Quantitative Electrocardiography (CSE) diagnostic pilot study is employed. QRS and ST-T segments a...

A rare presentation of caviar appendix in an Amyand’s hernia

Amyand’s hernia is a rare condition where the appendix is found within the sac of an inguinal hernia. The occurrence of an appendicular neoplasm within such hernia is even rarer. We highlight the case of a 70-year-old male who presented with an appendicular neoplasm masquerading as a strangulated inguinal hernia. The rarity and heterogenic clinico-pathological presentation of an appendiceal neo...

Modeling Autoregressive Conditional Skewness and Kurtosis with Multi-Quantile CAViaR

Engle and Manganelli (2004) propose CAViaR, a class of models suitable for estimating conditional quantiles in dynamic settings. Engle and Manganelli apply their approach to the estimation of Value at Risk, but this is only one of many possible applications. Here we extend CAViaR models to permit joint modeling of multiple quantiles, Multi-Quantile (MQ) CAViaR. We apply our new methods to estim...
