Thank you for the links too.Thank you for helping to bring the theory of statistics to everyday application !I’m wishing you had included an example of a t-test for equivalence. The sample distribution is discrete I would expect. h�bbd`b``� � Z� �

FSTA—Fund style analysis. 0000002987 00000 n First, it may be a good idea to bookmark this page, which will be easy to search with Ctrl+F when you're looking for something specific. Which statistical tests are good for Semi-supervised/ un-supervised data sets?I’m wondering how to check that “observations in each sample have the same variance” … Is there a test to check that ?You can calculate the mean and standard deviation for each interval.You can also plot the series and visually look for increasing variance.Is there a test similar to the friedman test? Could you give me some suggestions? I cannot recommend this, as if a student repeats that on a stat exam or on an interview led by a statistician, one’s likely to fail it.

Since the EUR carries the heaviest weight in the index, the EURUSD is the most affected in relation to the index. If we call the first quantity x i, with i label- Thank you.Sounds like you want a classification (discrimination) model, not a statistical test?Yeah, I think you are right.

Quick-reference guide to the 17 statistical hypothesis tests that you need in applied machine learning, with sample code in Python. RVC—Relative value correlation. Thank you.The test depends on the nature of the question you’re trying to answer.Practically ALL assumptions and ALL interpretations are wrong in this cheatsheet. The interpretation is wrong too.It’s worth noting there are over 270 tests, 50 in constant, everyday use, varying across industries and areas of specialization. I have two samples with different size (one is 102, the other is 2482), as well as the variances are different, which statistical hypothesis method is appropriate?
It looks as though there is a 100% negative correlation between the EURUSD and the DX.
