So the function simply looks like this,īut there is another mathematical approach of representing this, ![]() Let us consider a problem that a programmer has to determine the sum of first n natural numbers, there are several ways of doing that but the simplest approach is simply to add the numbers starting from 1 to n. Base condition is needed to stop the recursion otherwise infinite loop will occur.In every step, we try smaller inputs to make the problem smaller.Performing the same operations multiple times with different inputs.A task that can be defined with its similar subtask, recursion is one of the best solutions for it. It has certain advantages over the iteration technique which will be discussed later. Recursion is an amazing technique with the help of which we can reduce the length of our code and make it easier to read and write.

Risk factors identified across all techniques were vegetation for Ascaris spp., and cleaning oneself with water after defecating for hookworm. Model performance was similar across all techniques. Bayesian networks helped visualise relationships between variables and enabled interactive modelling of outcomes based on different scenarios for the predictor variables of interest. Recursive partitioning produced classification trees that visualised potentially at-risk population sub-groups. Recursive partitioning identified the most WASH and demographic risk factors, while Bayesian networks identified the most environmental risk factors. Mixed-effects logistic regression identified the fewest risk factors. and any hookworm species ( Necator americanus, Ancylostoma duodenale, and Ancylostoma ceylanicum). Outcomes of interest were infection with Ascaris spp. Baseline cross-sectional data from school-aged children in the (S)WASH-D for Worms study were used to compare risk factors identified from modelling the same data using three different statistical techniques. Alternative methods such as recursive partitioning and Bayesian networks can handle correlated variables, but there are no published studies comparing these methods with logistic regression in the context of STH risk factor analysis. Similarly, environmental factors including climate, soil and land attributes are often strongly correlated. Previously demonstrated risk factors including water, sanitation and hygiene (WASH) access and behaviours, and socioeconomic status are intrinsically linked. Identifying risk factors has mainly relied on logistic regression models where the underlying assumption of independence between variables is not always satisfied. Sustainable control of STHs requires understanding the complex interaction of factors contributing to transmission. Soil-transmitted helminths (STHs) are parasitic intestinal worms that infect almost a fifth of the global population.
