I have data with number of patients 100 mean 13.3 and standard deviation 2
I fit a Gaussian (shown in table) but the total number of patients is now different (49.8 vs 100), below is equation I used, could you tell me where I'm going wrong? Thanks
\(\displaystyle y\, =\, \dfrac{1}{\sigma\, \sqrt{2\pi \,}}\, e^{-\dfrac{(x\, -\, \mu)^2}{2\sigma^2}}\)
\(\displaystyle \mu:\, \mbox{mean}\)
\(\displaystyle \sigma:\, \mbox{standard deviation}\)
\(\displaystyle \pi\, \approx\, 3.14159...\)
\(\displaystyle e\, \approx\, 2.71828\)
concentration | number of patients | Gaussian |
9 | 3 | 1.98 |
11 | 22 | 10.30 |
13 | 46 | 19.72 |
15 | 19 | 13.90 |
17 | 8 | 3.60 |
19 | 2 | 0.34 |
total | 100 | 49.82 |
