- Canonical correspondence analysis (CCA) is a multivariate method to elucidate the relationships between biological assemblages of species and their environment. The method is designed to extract synthetic environmental gradients from ecological data sets

I think you should add explaination of the interpretation, at least to data what you haves used, in short. That will benefit many more. Increase your likes significantly.
Definitely
@@StatisticsBio7 is an interpretation of your data available??
Thank you again for this beautiful step by step guide & I must wait for the explanation, which I have to learn
Thanks for your comments and support
Thank you for making it simple and easy.
Thanks for ur sharing..really help me to analyzed my data..tq so much
Thank you Sir! You have no idea how much that helped me! THANK YOU!!!
Thank you very much for your brilliant video
Thankyou very much sir. Just what I was looking for and I found it.
Thanks for sharing... Need to know more about the interpretation of results.
definitely i will post interpretation
Thank you very much sir, it very helpful, please add its interpretation based on scores and arrows
thank you sir you have cleared all my doubts thanks alot🙌
Welcome
Really clear.Please i am eagerly waiting for the next lesson when you can the inteprete that graph. Thanks
Definitely one day I will upload video or post on blogger. Thanks for your support
@@StatisticsBio7 do you have the video explaining the interpretation for this graphs?
Follow the research articles. For environmental studies
Hello sir please kindly make a video on analysis and interpretation of the data.
It's been 3 years since you uploaded the video
Nice
thanku so much sir , very useful for me
Welcome
Hello sir I have six seasons with eight environmental variables and 35 species atlist of diatoms how to calculate in past software
Is only canonical correspondence analysis sufficient
Or go for other ordinations
Any model datas (dummy) send to me.
How to determine the number of environmental variables..I have a total number 16..
In my case, the species' names overlap with each other. I can't read the name clearly.
use a shortcut name for the species
Hello sir I have one problem if I have one problem if I use different symbols from past software, how to copy to add in footnotes
Eg if I use pink triangle to represent particular site then how I can copy it to add in footnote
Footnote add opection not available past software. So u try to any photos editing software and add to footnote...
Thank you for this beautiful guidance about this topic which i was searching for a long time. Could you please provide this software link so that i can download and use it.
Past freeware so just search google past statistics software. Or recently upload past 4.06b download video. Download link available in discription box
Hello sir, is it possible to analyze the data using the PAST4 application but the data is not balanced, namely 9 areas have rubbish and 6 areas do not? Can this case be simplified into an area with rubbish (a combination of all data from 9 areas where there is rubbish) and an area without litter (a combination of 6 areas where there is no rubbish), what kind of data analysis should I use for this case? Thank You
This is possible in grouped CCA analysis. Find out if related research papers have already have been published?. But grouping CCA analysis is not possible for PAST 4 Version. Thank you for posting your doubts.
Hi Sir, thank you for this very explanatory video on CCA, I tried the link but its expired, could you provide a new one for the software.

Thank you Sir for your awesome video, could you show us how to plot phylogenetic tree using Origin if we have Newick tree plz?
Hello sir you have explain one dayaset for environmental variables and species
If we have data of three different locations of whole year even species are different at location
i.e. if we study three reservoirs for different seasons and dataset is available for each reservoir for environmental variables and species. How can we compare in PAST
Hi Sir, thank you so much for the video. I dont know how to intepret the data from the graph and value, how can I know which axis is correlated to the environmental parameters?
Interpretation follow the reference papers
How to interpret the graph?
Follow the ur work related research articles
I had a problem to do the analysis, I selected the environmental parametres, but when I ran the CCA, it did show me a message that said: "SVD did not converge". How I can fix that?
Can u send ur data samples
@@StatisticsBio7 Thaks for your reply, I fixed the mistake, I had two variables were not included in the analysis, due to their incappability to calculate the variance. But now my doubt is with the length of the triplot, because the software gives me a determined size, but I have seen in other videos that they can increase this size to watch the association of variables, but I don't know if this is correct to do.
How to adjust overlapping labels in PCA biplot?
Already explain for overlapping methods on this video
Does it gives r2 and p value?
No
@@StatisticsBio7 how people have reported these value
Analysis for correlation and regression
@@StatisticsBio7 ok thank you
@@StatisticsBio7 is this available when cca is done with R or other software?
Can we find PCA with these data? Suppose if the winter season has no species occurred, can we put the value 0? Does it affect the result?
No but some times maybe possible
@@StatisticsBio7 Could you please help to find out this?
Can u send ur sample data files
what is the name of the software program you are using
Past statistical software
Sir can u teach ANOVA and Correlation in PAST
Definitely I post on videos. thanking you for your comments.
hello sir please tell me how to explain the figure of CCA
Just follow the research papers compare to ur data
@@StatisticsBio7 thank you so much sir for your reply
Thank you for your support Prachi Rathi 👍
Hello sir when I analyse my samples it comes a dialogue box
At least 2 rows, 2 environment. and count data columns required
Which I can not able to understand
no problem. can you send to me your data samples. I check it. Or any dummy data samples send to me
As my problem is I have eight variables studied in six seasons at five different sites so total samples are 30
So when I select data from CA
I add number of variables then a dialogue box appeared which shows
A least 2 rows, 2 environment and 2 data columns required
Which I did not understand
Two type of variables one environment and another one species variables. U say eight variables so enter the value eight
@@StatisticsBio7
Hello sir I add 8 but same problem
Ajay Rana I want see ur data file. So make dummy data send to me. I try to analyse and solve ur error
Sir please put the interpretation of CCA graph
Just follow ur work relevant research papers
G’day! I’m working on a certain fish species distribution, is there a particular way I can come up with some Fig. about the developmental stage and body length frequency?
we have to transform the data before analysis. The calculation is totally wrong.
How do you say
@@StatisticsBio7 Hello sir, before analysis, we have to normalize the data by transforming abiotic and biotic data.

Sir can you please explain ho to interprete this in word
Follow reference paper
Ok sir can we perform.correlation coefficient with species data
ya it's possible. CAA also explain for species relationship with comparison for environmental variables .
Sir can u please make video on it cause I want it for my research paper
What statistics do you want to use for your research?
Hello, How can I get the software
It's freeware software. So search Google past statistics software download
@@StatisticsBio7 Thank you please send me some tutorials on PAST
Add our telegram channel statistics bio7. I send to u
How to interpret this CCA graph
Thank you for your comments. Very shortly I start blogger and full explanation for interpretation and ete for all my Statistics videos. but u very urgent just follow reference paper
Just follow the webpage

@@StatisticsBio7 Tq for the speedy reply sir
Sir how to load environmental factors at more than two or three sites with abundance of species at different sites
Your data analysis in different seasons and sites or different sites only. Sites type to y axis
hello kindly resend the telegram link it has expired
