Author Correction: Investigating the drivers of the spatio-temporal patterns of genetic differences between Plasmodium falciparum malaria infections in Kilifi County, Kenya

An amendment to this paper has been published and can be accessed via a link at the top of the paper.

In addition, the original version of this Article contained a repeated error, where the mean distance was calculated incorrectly. The mean of a half-normal distribution should not be σ , but 2 π σ . Therefore, the mean distance between parent and offspring infections should be multiplied by 2 π = 0.798 . These changes do not affect the main conclusions of the original Article.
As a result, in the Abstract, "The mean geographic distance between parent and offspring malaria infections for the base model was 0.5 km (95% CI 0.3-1.5), for a distribution with 68% of distances shorter than the mean. " now reads: "The mean geographic distance between parent and offspring malaria infections for the base model was 0.4 km (95% CI 0.24, 1.20), for a distribution with 58% of distances shorter than the mean. " In the Methods, "Therefore, the mean distance between parent and offspring infections is given by σ, and 68% of distances are shorter than this value (Fig. 1) www.nature.com/scientificreports/ "The mean distance between parent and offspring infections is given by σ √ 2/π , and 58% of distances are shorter than this value (Fig. 1). " "We simulated data with known values for the mean distance between parent and offspring infections, σ, and probability of recombination, p r , and then applied the method to the simulated data to see how well the known values could be recovered. " now reads: "We simulated data with known values for σ , the parameter for the distance between parent and offspring infections, and probability of recombination, p r , and then applied the method to the simulated data to see how well the known values could be recovered. " In Table 1, "mean distance between parent and offspring infection". now reads: "parameter for distance between parent and offspring infection, (mean = σ √ 2/π ).
In Figure 1, the dotted lines marking the mean of distribution were incorrect. As a result the Figure  In Table 3, "mean distance between parent and offspring infections (in kilometers)". now reads: "parameter for the distance between parent and offspring infections (in kilometers)**".
As a result, in the Table legend, "Simulated scenarios. *The base model scenario is indicated by bold font. " now reads: "Simulated scenarios. *The base model scenario is indicated by bold font. ** The mean of a half-normal distribution is given by σ √ 2/π. " In the Results, "The method was able to recover known values from simulated data for the mean distance between parent and offspring infections and the probability of recombination (Fig. 2). The model could reproduce reasonable estimates for the mean distance, but the estimates were less precise if the mean distance was 2.0 km or greater. For longer mean distances, the size of the area simulated may limit the accuracy.

The maximum log likelihood values, a measure of the goodness-of-fit, were similar for the model variants. " "However none of these factors substantially influenced the estimated mean distance between parent and offspring infections (Fig. 8).

" In Table 4 As a result, in the Table legend, "*The mean distance refers to the standard deviation of the positive half of a normal distribution centered around zero. In all cases, the probability of a short distance is highest and 68% of parent-offspring distances are shorter than the mean value (Fig. 1). " now reads: "*The mean of a half-normal distribution is given by σ √ 2/π ) . In all cases, the probability of a short distance is highest and 58% of parent-offspring distances are shorter than the mean value (Fig. 1) In the Discussion, "The range of possible values for the mean distance between parent and offspring infections in our study ranged between 0.3 km (0.3 km-1.5 km) and 1.0 km (0.5 km-2.5 km) for the different model variants. These results are consistent with these previous findings, since with the distribution used, 68% of the distances are less than the mean and 38% are within half of the mean distance. "
