Maximum likelihood estimators for the mean and variance of a truncated normal distribution, based on the entire sample from the original distribution, are developed. The estimators are compared with ...

This paper obtains and explores a family of confidence procedures for the mean of a normal distribution which are, in a certain sense, more efficient than the usual procedure. Let X (possibly a sample ...

How to Calculate Variance in Excel To calculate variance in Excel, you will need to have your data set already entered into the software. Once you have your data, you can choose your formula based ...

ABSTRACT Expanding the realized variance concept through realized skewness and kurtosis is a straightforward process. We calculate one-day forecasts for these moments with a simple exponentially ...
