 Jun 9 awarded Popular Question Feb 9 comment Convert linear SVM answers to class probability? See also my comment here for a literature reference. Feb 2 comment Interpretation and usage of Kolmogorov-Smirnov Test in Python But why do you want to standardize your data, in the context of using the KS test? Feb 2 comment Interpretation and usage of Kolmogorov-Smirnov Test in Python So, the general approach is subtract the mean and divide by the standard deviation; that is, $x_{new} = \frac{x - \mu}{\sigma}$. You can use the code in this SO answer to standardize your data. Jan 5 comment Implementing Neural Network for time series Ah, I am very sorry then, but your estimation that research has dropped off is most likely correct. However, as I'm sure it seems to you, it seems likely to me that the multivariate case would at least be as impacted by seasonality/trend as the univariate, if not more so. Jan 5 answered Implementing Neural Network for time series Jan 3 revised Is it possible to do a test of significance for a string occurrence in two datasets deleted 14 characters in body Jan 3 comment Is it possible to do a test of significance for a string occurrence in two datasets @Glen_b, I think the OP wants to know if it is possible to separate their set of words into 2 classes: words which have roughly the same count in both groups and words which don't. They don't know how to identify the group of words which don't have roughly the same count and moreover do not know how to define the term 'roughly'.

See this, this and this as well. Jan 1 comment Implementing Neural Network for time series You should look at the R forecast package, specifically method nnetar by Rob Hyndman for other insight into how people have dealt with this. Dec 30 comment Confusion about hidden Markov models definition? You may want to read a more in-depth tutorial than the Wikipedia page. 'A Tutorial on Hidden Markov Models and Selected Applications in Speech Recognition' link by Lawrence Rabiner seems to be a good choice. Another, shorter work that is also a good introduction to the subject is 'What is a hidden Markov model?' by Sean Eddy. Dec 29 comment Confusion about hidden Markov models definition? The foundational concept being missed here is the difference between probabilities of transitioning between states and actualizations of random variables, as in the first comment in response to your post. Dec 28 answered Confusion about hidden Markov models definition? Dec 22 comment Find correlation between 2 non-ordered variables @Abbas, some questions: are the 10 individuals and the cell lines surveyed the same in both expression and methylation studies? If so, do the methylation and expression studies survey roughly the same time point in the cell cycle, if that is relevant (i.e. methylation as pertains to meiosis)? Dec 20 comment Find correlation between 2 non-ordered variables That's what I thought. I think you underestimate the quantity of people on this site conversant in subject-specific areas such as biology. Please describe in more detail, as your comment 'which treatment' suggests that there are multiple treatments, which I cannot map onto your initial problem of 1 hospital, 1 measurement of doctor absenteeism. Dec 20 comment Find correlation between 2 non-ordered variables What is gene 'position'? Dec 20 comment Find correlation between 2 non-ordered variables If the example given is not the full story, I think that giving more information about your data might help us help you more.
