“Increase sample size until statistical significance is reached” is not a valid adaptive trial design; but it’s fixable.

TLDR: Begin with N of 10, increase by 10 until p < 0.05 or max N reached. This design has inflated type-I error. Lower p-value threshold needed to ensure specified type-I error rate. The number of interim analyses and max N affect the type-I error rate. Threshold can be identified … Read more“Increase sample size until statistical significance is reached” is not a valid adaptive trial design; but it’s fixable.

Forecasting Time-series with Multiple Seasonal Patterns

Forecasting time-series which contain multiple seasonal patterns requires flexible modelling approaches, and the need for continuously updating models emphasises the importance of fast model estimation. In response to shortcomings in current models, a new model is proposed which brings the desirable qualities of speed, flexibility and support for exogenous regressors into a state space model.
