Weighted percentiles in many areas can be used to investigate the overall trend in a
particular context. In this article, the confidence intervals for the common percentile are …

The log-normal distribution is often used to analyze environmental data like daily rainfall
amounts. The rainfall is of interest in Thailand because high variable climates can lead to …

In this article, we propose approaches for constructing confidence intervals for the single
signal-to-noise ratio (SNR) of a log-normal distribution and the difference in the SNRs of two …

Novel approaches were proposed for constructing simultaneous confidence intervals for all
differences of coefficients of variation of log-normal distributions, using the method of …

Herein, we propose the Bayesian approach for constructing the confidence intervals for both
the coefficient of variation of a log-normal distribution and the difference between the …

Log-normal distribution is used widely in application fields such as economics and finance.
This paper considers confidence interval estimates for common signal-to-noise ratio of log …

Recently, harmful levels of air pollution have been detected in many provinces of Thailand.
Particulate matter (PM) contains microscopic solids or liquid droplets that are so small that …

The Weibull distribution serves as a versatile tool for modelling various types of data,
including reliability analysis, failure rates, survival analysis, and extreme value analysis …

This study presents two statistical methods for testing the signal-to-noise ratio (SNR) of a log-
normal distribution. The proposed statistical tests were based on the generalized confidence …

This study presents three methods for testing the difference between two signal-to-noise
ratios (SNRs) of log-normal distributions. The proposed statistical tests were based on the …
