标准正态分布分位数英文
truncated normal distribution    The quantiles of the standard normal distribution are commonly referred to as z-scores in English. These quantiles represent the values at which a given proportion of the distribution lies below the value. For example, the 0.95 quantile of the standard normal distribution corresponds to a z-score of approximately 1.645, indicating that 95% of the distribution falls below this value. Similarly, the 0.99 quantile corresponds to a z-score of approximately 2.326, and so on. The z-scores are widely used in statistical analysis and hypothesis testing to determine the significance of observed values in relation to the standard normal distribution.
