a group of equal proportions - the definition of quantile is one of a class of values of a variate that divides the total frequency of a sample or population into a given number of equal proportions
1 answer
Yes.
Usually the value of the lower quantile, median, and upper quantile are in ascending order, how if for the particular set of data, if all values are the same, then these three measures can be the same.

In the context of "q125," the "q" typically stands for "quantile," which is a statistical term used to describe the division of a dataset into equal intervals. The number 125 indicates a specific quantile, often referring to the 125th quantile, which might represent a specific data point or threshold in a distribution. However, in many contexts, particularly in statistics, quantiles are usually expressed as fractions or percentages, so the precise meaning can vary depending on the specific application.

Quantile regression is considered a natural extension of ordinary least squares. Instead of estimating the mean of the regressand for a given set of regressors, and instead of minimizing sum of squares, it estimates different values of the regressand across its distribution, and minimizes instead the absolute distances between observations.

In statistics, a quartile is a type of quantile that divides a data set into four equal parts, each containing 25% of the data. For example, if you have a set of test scores, the first quartile represents the score below which 25% of the scores fall. Understanding quartiles helps in analyzing the distribution and spread of data.

In mathematics, ( Q_x ) typically denotes a quantile function for a random variable ( x ). It represents the value below which a given percentage of observations fall, effectively providing a threshold for probabilities. For instance, ( Q_{0.5} ) would indicate the median of the distribution. The specific meaning can vary based on context, so it's important to consider the surrounding definitions.

If the exponential distributions have the same scale parameter it's known as the Erlang-2 distribution. PDF and CDF exist in closed-form but the quantile function does not.
If you're looking to generate random variates the easiest method is to sum exponentially distributed variates. If the scale parameter is the same you can simplify a bit: -log(U0) - log(U1) = -log(U0*U1).
