Hi..i am absolutely beginner.... i have only presence data... but what i am watching in different videos , people are taking background data for MaxEnt software? from where it come. Do Maxent automatically generate this background file. If not then how can i make background data file especially in MaxEnt software.....? is it possible to separately make file in R and then used that file for MaxEnt software..

Thank you so much sir. I am planning to take niche distribution modelling and climate change as my research topic, your vedioes proved very benificial for me. All my concepts got cleared and now i fully understand this very topic.

Thank you for your lecture. I have one question how can we eliminate multicollinearity in the environmental variable.

First, run Pearson correlation within all your independent variables and, ideally, any two variables with r > 0.8, you should drop one. To decide on which one to drop, check their contribution/importance in explaining the distribution of your species (easy to do in MaxEnt) and drop the less important one.

If you have variables that are highly correlated you'll want to discard the redundant ones and construct the model without them

Hi, you can either build a correlation matrix for your variables and select the least correlated variables (usually, -0.7 < r < +0.7) or use the Variable Inflation Factor in the usdm package: cran.r-project.org/web/packages/usdm/usdm.pdf

Around the 14 minute mark, you referenced an author by the name of "Liu" as additional literature to read about presence and absence data. Can you clarify his full name and potentially a publication that you would recommend?
