This approximation is much faster but may lead to instabilities at initial steps, where a limited number of observations can skew the mean towards values with very high magnitudes. This would then influence the subsequently calculated posterior means. To overcome this instability, the posterior update...
Just as the VIX and the SKEW index quantify the volatility and the tail risk perceived by today's investors, the resulting LIX index measures, in a similar market-implied fashion, the liquidity risk. The maximum likelihood estimation of popular mean-reverting processes applied to model-free ...
Simply fixing the regularization complicates rather than simplifies the selection of the best candidate model and in the worst case may even skew the results for other selection parameters. Therefore dynamical modelling of galaxies with an a priori fixed amount of regularization should be avoided if ...

[21] introduced the multivariate skew-normal distribution. Likewise, for the log-BS regression model, Lemonte [22] proposed the multivariate BS regression model, Kundu [23] studied the bivariate SHN distribution, and Martínez-Flórez et al. [24] considered the asymmetric multivariate BS regression...
The Black-Scholes model requires five input variables: the strike price of an option, the current stock price, the time to expiration, the risk-free rate, and the volatility. The Black-Scholes model is usually accurate but it makes certain assumptions that can lead to predictions that deviate...
In particular, we show that the IPCA factors can be rationalized via an economically plausible three-factor model consisting of a level, slope and skew factor. Finally, out-of-sample trading strategies based on insights from the IPCA model have significant alpha over previously studied option ...

Duplicate Values: Duplicate records in the dataset can skew results, leading to incorrect model outcomes by over-representing certain observations. A thorough check was conducted to identify any duplicate rows. After determining whether any entries in the data were duplicates, values were eliminated. ...
