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 ...

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 ...

Discover what a log-normal distribution is, its financial applications, and how to calculate it, including using Excel for practical financial analysis.

Pickering 12 reanalysed the population's BP distribution and suggested that positively skewed standard normal curve showed importance of environmental influences in hypertension.

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 ...
