Hi,
I have weather data into my elasticsearch from different weather forecast sites. In practice i use (scrapy) spiders in order to crawl the data from the sites and store them to elasticsearch.
The index field structure contains fields like temperature, humidity, etc and one more field called source where i store the site (name) which the element belongs to.
I was thinking if it is possible to create a correlation matrix (based on source field,so the columns of the correlation matrix would be the different source's field values) comparing each site's temperature differences, with the rest ones.
Any Ideas?
