Step 1: split the data into groups by creating a groupby object from the original DataFrame; Step 2: apply a function, in this case, an aggregation function that computes a summary statistic (you can also transform or filter your data in this step); Step 3: combine the results into a ...

applysplitdata analysisMany data analysis problems involve the application of a split-apply-combine strategy, where you break up a big problem into manageable pieces, operate on each piece independently and then put all the pieces back together. This insight gives rise to a new R package that ...

Therefore, follow-up surveys may be necessary if the data indicate that the first sample was too small. However, the effect of multiple sampling on allele frequency estimates and the accuracy of the method is poorly understood. Here we trapped drones from two independent DCAs every month over ...
