Loved the explanation very much. Thank you Prof Hassan. Really Appreciated.
thank prof so much. It help me very much
sir can i know how can i do apply this method to large data set its bit urjent sir can u plz reply fast
Can i calculate sens slope for data collected at irregular intervals?
This was very helpful, thank you!
ThankYou!
Thank you Prof for the video. I would like to know if the Zs value represent the magnitude of change in the trend?
could you please tell, how to interpret this data. As I can see the sen's slope is 0.33. Is there any significant value we should consider? Thank you
thank you very very much!
Sir why put +sign instead of= sign in formula
Thank you professor 😊
Thank you professor 😊
Sir If two variables are taken, instead of 1,2,...12, can I insert independent variable data Kindly reply sir
Thanks for you explanation, Prof. It really help me proceed my data manually 🙏🏼👍🏼
Indeed an excellent explanation Sir. I have one question regarding rainfall data where 0 is repeatedly possible as a value for some months. In such cases also, we will count them for variance calculation or not. Kindly explain the case. Thank you.
Thank you for the explanation. However, I would like to know if you have more than 30 years data, how would I get t1 and t2 values without having to manually look at the data.
I also want to know the same thing
When I write the formula with the help of ifs, it gives an error and says you have entered too few arguments for this function.please help me
Really excellent
Excellent Professor
Thanks Prof.
Salam alaikom sir Hassen i need calculate p value for Time séries Can you to make that by excel wa jazaka Allah khairan
this table work all type data or different data. we can conclude results based on this table.
How do we create the graph of the you slope method?
How do we create the graph of the you slope method?
How did we get the variance formula, is there a derivation for that?
And then, and then, and then, so then, and then(!) Putting that aside, very nice presentation of Mann-Kendall.
I highly appreciate your comments.
Thank you very much for the step by step explanation.
Thank you so very much
What should we do if we have both duplicate and triple repetitions in the data we have?
Really helpful video, thank you! I’ve been struggling to understand this for a while but you explained it very clearly
Thank you very much for your tutorial. Questions were asked about t1 and t2. What is the selection rule? Lowest and highest repeated values? The lowest values that repeat twice or the lowest values that repeat three times? Thank you very much for the answer.
If there is more than 2 pair, how should i do?
I am not sure about your question. However, we always try to estimate the trend as a function time (e.g., year). Thus, we have to determine the trends for each of the variables separately as a function of time. Thanks.
if there is no pair then what should I do?
Then, please ignore the entire term associated with ti. Thanks.
@@profqkhassan Thank you Sir
Thanks for your explanation!
Thank you so much, very well explained.
If there is more than two pair group, So what will be in that situation???
well done
Nice one thanks teacher
thank you
where can I find this table that relates the Z-value and the confidence level?
You may Z-value and their corresponding confident level at www.dummies.com/article/academics-the-arts/math/statistics/finding-appropriate-z-values-for-given-confidence-levels-147216/ Thanks.
What is tau in mk test?
thank you so so so much professor.
Excellent explanation with many thanks.
Sir please tell about how to do (percent change in mean )and how to perform (Pettit test) .. please sir .your videos are really helpful..
If you give formula for computing how many times repeated each number in case more dataset
Excellent explanation
Sir, if formula inserted can you give in comment as vedio unable to see properly
thank u sir
Perfect
Very helpful, thank you!!!
