<p>This function calculates the log-likelihood of GARCHSK model.</p>

Functions for estimating a GARCHSK model and GJRSK model based on a publication by Leon et,al (2005)<doi:10.1016/j.qref.2004.12.020> and Nakagawa and Uchiyama (2020)<doi:10.3390/math8111990>. These are a GARCH-type model allowing for time-varying volatility, skewness and kurtosis.

garchsk_lik: This function calculates the log-likelihood of GARCHSK model.
