Re: detect peaks and valleys
Hi;
I drew arrows to the peaks in post #20.
To decide you need the data.
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Do you have the data values? That is how you determine it.

Re: detect peaks and valleys
Count up each type of data value the way I did in post #4. That is how you get those peaks and valleys. You do not need the histogram.

Re: detect peaks and valleys
The histogram is for the eye to get an idea what the data looks like. The data itself is the best thing.
Look at post #4, the data.
There
4 ones
1 two
1 three
3 fours
you do the rest. You will see there are more ones than anything else. That is a peak.

Re: detect peaks and valleys
ok but i am asking about probability .
How can we compute probability of each bin ?
Also how can we compute Bayesian formula in histogram post #1 .
As Bayesian formula can show that posterior probability is proportional to density value .

Re: detect peaks and valleys
Hi;
Just take how many is in that bin and divide it by the total number.

Hi tina123;
I do not understand either term. You will have to explain to me what they mean.

Re: detect peaks and valleys
Hi;
I am sorry but I can not apply Bayes theorem here. What question is being asked? I do not know. Hard enough to solve a problem but having to guess at what it is, is too tough.
Please go here so you can ask a specific problem:
