How to find the mean of the probability distribution (or binomial distribution). Hundreds of articles and videos with simple steps and solutions. Stats made simple!
Unless your goal is to somehow improve on what is already written, or you simply don't have those existing tools, then you should never be reinventing the wheel. Use existing code, for example, regress is in the stats toolbox. Or you could even use my polyfitn f...
N --> no.of the observations / data points r --> assumed corr.coef t = r*sqrt((N-2)/(1-r^2)); % find t-statistics p1 = 1 - tcdf(t,(N-2)) % find pvalue using Student's t cumulative distribution function for one sample test. https://www.mathworks.com/help/stats/tcdf...

compute t-stats and p-values after qreg. I adapted the bootstrap code to stata 9, but got an error message. Is something wrong with the syntax or is stata 9 to be handled differently? Bonus Question: Is there a simpler way of obtaining t-stats and p-values in ...
To move to the desired functions key the first letter of its name (without keying ALPHA first). The function's syntax is displayed in the status line. All further mention of the functions assumes they are being used from the Stats/List Editor screen. Managing Lists Using the List Editor p...
Regarding 'stats' I have the following questions: 1) What is the critical value (alpha) for the F statistic? I mean which value does Matlab 'assume' (e.g. alpha=0.01, alpha=0.05...)? 2) How does Matlab compute the p-value? The p-value(which should be ...
P-values can be calculated from a cumulative distribution (norm.cdf()fromscipy.stats) which represents the probability of obtaining a value equal to orless thanthe one observed. Then to calculate the p-value we calculate1 - norm.cdf()to find the probabilitygreater thanthe one observed:...
So supponing that the field with the traffic to monitor i "bytes" and the field with access and failed is "action" and that you want thes monitoring for each host, you could try something like this, for a month: <your_search> | stats max(bytes) AS peak count(eval(action=...
