But the output of area calculation is very low e-9 I used the UTM projection for zone 45N please help me.. Even when I change the projection to WGS84 the area remains the same Can you tell me what is wrong

    Hello, thanks for uploading this video. It is very useful. I would like to ask what is the reason for a negative value in the LCBD of the replacement component. Is there a link where I can find this information? that would be perfect actually. I am working right now on my thesis and I got a negative value, and I do not know the reason behind this. You can see this in the minute 41:35 of the video. Thanks in advance.

    My favorite layout: Source top left, console top right. History bottom left and completely minimized because it's needed the least consistently, everything else in bottom right. You get a super tall source pane, a larger console, and everything else can be resized when needed

    Hello. Great video! I saw that in the calculation of LCBD the value of site 1 is negative. The same thing happens to me with my data (some values are negative). This is correct? According to the calculations, it should not give values between 0 and 1? What am I doing wrong? Thank you!

  • @nurfiliz838
    @nurfiliz838 2 года назад

    Thank you for the great lectur! But i didnt understand the sites/observation issues. For example lets say i have 2 sites with 30 observations, and i want to know the beta diversity between these sites over these observations, so how the code understands that which observations are from first site or second site so it gives a B-div value? Thanks in advance

    • @rachitsingh98
      @rachitsingh98 2 года назад

      I think you have to organise the data such that the "Site" is in rows and the columns will have your count data for your species. It will then calculate one value for the whole row 1, which could be site A and then there will be a calculation on site B (row 2). Correct me if I am wrong!

    • @rachitsingh98
      @rachitsingh98 2 года назад

      Ahh, I see what you meant. Actually I think here the data was not sub-set to compare differences between 2 sites, but just taken the overall value. In your case (I did this too), you would have to subset the data to only get your first two categorical variables (sites) and then calculate B-div between them...and so on.
