We checked the number of per week unit conversion process off levonorgestrel emergency birth prevention in the us for every single 1000 female old fifteen-49. I reviewed these types of a week sales investigation that with an autoregressive incorporated swinging mediocre (ARIMA) regression to choose if or not retail transformation out of levonorgestrel crisis birth-control notably increased for the tested vacation attacks.

The brand new presumption regarding increased sales adopting the New year vacation is considering several possible risk items (enhanced sexual behavior, decreased accessibility contraceptive through the intercourse, improved prices away from sexual assault, and you may possibly restricted use of contraceptive)
The ARIMA modeling processes consists of about three iterative tips: personality, estimate, and you will symptomatic checking.47 Based on the you can easily ARIMA designs understood out-of study of the new autocorrelation and you can partial autocorrelation services, model selection of a maximum model is often centered on reducing Akaike pointers criterion and Schwartz bayesian standards.
