Understanding histogram_quantile based on rate in Prometheus

问题 According to Prometheus documentation in order to have a 95th percentile using histogram metric I can use following query: histogram_quantile(0.95, sum(rate(http_request_duration_seconds_bucket[5m])) by (le)) Source: https://prometheus.io/docs/practices/histograms/#quantiles Since each bucket of histogram is a counter we can calculate rate each of the buckets as: per-second average rate of increase of the time series in the range vector.

Calculating percentile for each gridpoint in xarray

只愿长相守 提交于 2021-02-17 06:07:38
问题 I am currently using xarray to make probability maps. I want to use a statistical assessment like a “counting” exercise. Meaning, for all data points in NEU count how many times both variables jointly exceed their threshold. That means 1th percentile of the precipitation data and 99th percentile of temperature data. Then the probability (P) of join occurrence is simply the number of joint exceedances divided by the number of data points in your dataset. <xarray.Dataset> Dimensions: (latitude:

How to calculate a percentile ranking of a column of data relative to another column using python

梦想的初衷 提交于 2021-02-07 14:19:44
问题 I have two columns of data representing the same quantity; one column is from my training data, the other is from my validation data. I know how to calculate the percentile rankings of the training data efficiently using: pandas.DataFrame(training_data).rank(pct = True).values My question is, how can I efficiently get a similar set of percentile rankings of the validation data column relative to the training data column? That is, for each value in the validation data column, how can I find
