GCSE OCR Other graphs - OCR Sketching graphs The most commonly occurring graphs are quadratic, cubic, reciprocal, exponential and circle graphs. Their equations can be used to plot their shape.

Given these backgrounds, applying the exponential random graph model to unique investment data of Japanese VC firms over the last two decades, we empirically examine the relationship between VC firm ...

We study the asymptotics for sparse exponential random graph models where the parameters may depend on the number of vertices of the graph. We obtain exact estimates for the mean and variance of the ...
