I downloaded the Jamovi software and the PAMLj power analyses module and set the following paramters (basing it off what we chose to use for G*Power and thistutorial).
General linear model power analysis.
Expected partial eta squared: 0.15
Effect df: 3
Model df: 3
Minimum power: 0.8
alpha: 0.05
library(TOSTER)
powerTOSTpaired(alpha = 0.05, statistical_power = 0.9, low_eqbound_dz = -0.4, high_eqbound_dz = 0.4)Warning: `powerTOSTpaired()` was deprecated in TOSTER 0.4.0.
ℹ Please use `power_t_TOST()` instead.The required sample size to achieve 90 % power with equivalence bounds of -0.4 and 0.4 is 68 pairs[1] 67.63859I can’t get it to work.
Run the model on the pilot data:
studyTimeGlm <- glm(mean_StudyTime ~ condsFile,
data = study_time_FR,
family = inverse.gaussian(link = "identity"))Run the simulation:
