1. ### Non-linear comparisons

Thank you again! Each sheet has two versions of the data, just transposed. I was using the second form with the sample number on the left and the allele number across the top.
2. ### Non-linear comparisons

Ok, I will look into it, thank you! More and more learning. In the mean time I was wondering what your experience is with Euclidean distance calculations. I have a program that I am developing that calculates these for a Bioinformatics program and my results in Excel and in the program seem...
3. ### Non-linear comparisons

I attribute the kinks to inconsistencies in the data collection. I have other data that is being collected that is much better controlled as far as the collection. This was the first year and we were working out the kinks. However, that said the r-squared for each line using this data was...
4. ### Non-linear comparisons

This may be a job for R but I will look into that. In the data I have been analyzing has an N=22. The analysis you did above makes sense when looking at the attached graph. There seems to a break out into two groups, with Duke being the one furtherest away from the "main body? Now here...
5. ### Non-linear comparisons

Ok, Kat. It took a while but here are the results of the SD calculations. Duke is a clearly out of whack and I need to go back and look at the original data but the others seem pretty consistent. I am assuming the units are days here. Variety Aurora Standard Error: 0.03783832826315897...
6. ### Non-linear comparisons

Whist I digest that amount of information i will tell you that if you have a windows 10 machine, if you go to Windows Accessories, there's an app called Keycaps. If you one that you will see all manner of "hidden" characters. All you do is highlight it, click select, then click copy. Then go...
7. ### Non-linear comparisons

Ok, I think I have it for all six varieties. The numbers are different because I used a more complete dataset, and there are the same number of data points for each variety, even if that value was zero. And the Results are Row │ variety a b c t50...
8. ### Non-linear comparisons

Is Bias the same as SE with Jackknife results? Jackknife statistics Estimates Bias a 4937.931475 7.16936606 b 12.842378 3.05857135 c 0.959727 0.03206308 ------ Jackknife confidence intervals Low Up a 4868.2965580 5007.566392 b...
9. ### Non-linear comparisons

Yes that is the number of days that I calculated also. I know what you mean about the R code. It is something that I am trying to learn but it is often counter intutitave but I don't know if that is the stats jargon or just my poor programming skills. Just one quick question, what is...
10. ### Non-linear comparisons

There seems to be several options for the Gomphertz Curve. I am going to dig into those and see what I can find out about SE
11. ### Non-linear comparisons

Actually I had 12 datapoints. See the attached Excel file. Geeze, you're forcing me back into my notes pretty far. the formula is t=ln(ln(y/a)/-b)/-c where y/a is the proportion of the emergence you are looking for, so if you are looking for the time when 1/2 of the emergence has occurred...
12. ### Non-linear comparisons

katxt, Thanks for the response I used R with the non-linear analysis package eznls. Here is the output: Jerseymodel=nlsfit(Jersey_Round_1,model=10,start=c(a = 4000 , b = 1, c = 0.34)) > Jerseymodel $Model [1] "y~a*exp(-b*exp(-c*x)"$Parameters Count per_total...
13. ### Non-linear comparisons

I have insect emergence data that comes from 6 different varieties of plants and the curve very much fits a Gompertz curve formula. I want to statistically compare the 6 to see if there is significant difference of the timing of the emergence between the cultivars. When I run an ANOVA on...
