Spearman Rank Correlation Coefficient
A non-parametric statistic used to measure the agreement between two rankings, ranging from -1 to 1, with values closer to 1 indicating greater concordance between the two rankings. It is commonly used to assess ranking consistency across different versions of a benchmark.
Timeline (last 90 days)
Ranking consistency is a metric in recommender systems and information retrieval for measuring ranking quality, commonly quantified using Kendall's tau or the Spearman rank correlation coefficient, comparing the degree to which the pairwise orderings of the model's ranking and the true observed ranking agree.
IC (Information Coefficient) is essentially the Spearman rank correlation coefficient between a factor's predicted values and actual future returns, with a value range of [-1, +1].
