Chicago Animal Care and Control protects public safety and ensures the humane care of animals through sheltering, pet placement, education and animal law enforcement. A picture of you and your pet together. If you become separated, a picture of you and your pet together will help you document ownership and allow others to assist you. Add species, breed, age, sex, color and distinguishing characteristics. However, the evidence is contradictory. While some research has shown that pets do increase some aspects of health, more recently the opposite has also been found.
Additionally, there has been a great deal of debate about how to select a model to derive the weights. A sophisticated propensity score weighting method using generalized boosted regression, a data-adaptive, nonparametric logistic regression technique was developed at the RAND Corporation which can accommodate complex and nonlinear relationships between covariates and treatment selection 46 The weights created using boosted regression provide the estimated conditional odds of receiving treatment where Xi is the vector of control variables and p(Xi) is the estimated conditional probability of receiving treatment for an individual with control variables equal to Xi. We believe this approach is most appropriate for causal analyses that model outcomes of pet ownership because the type, strength, and form of the relationship between the predictors and ownership (e.g., treatmentâ€) have not been empirically established.
The recent review of the research literature on the impact of pet ownership on health concluded that there is not enough evidence to make any conclusions 3 The piece reviews the methodological challenges preventing the extant literature from building a strong research base, including problems with small samples, convenience samples, lack of methodological rigor, and self-report measures, and the file drawerâ€ effect. All the research to date suffers from several limitations that prevent any strong conclusions about the … Read moreRead More →
