In the prediction of genetic values and quantitative trait loci (QTLs) mapping via the mixed model method incorporating marker information in animal populations, it is important to model the genetic ...

In this paper, a local 𝑀-estimation for the conditional variance function in heteroscedastic regression models under stationary α-mixing dependent samples is developed. The local 𝑀-estimator is ...

We propose a new combined semiparametric estimator, which incorporates the parametric and nonparametric estimators of the conditional variance in a multiplicative way. We derive the asymptotic bias, ...

The exponentially weighted moving average (EWMA) estimator is widely used to forecast the conditional volatility of short-horizon asset returns. The EWMA estimator is appropriate when returns are ...

Conditional formatting highlights key information in a spreadsheet so it’s easy to see at a glance. This beginner’s guide gets you started. Spreadsheets usually hold a wealth of information, but it ...
