Core simulation

Required-sample-size searches and power curves for balanced designs.

Achieved power and effect-size sensitivity at a fixed sample size.

power_achieved(): Estimate achieved ANOVA power at a fixed sample size
power_sensitivity(): Estimate ANOVA effect-size sensitivity at a fixed sample size

Calculation-only analyses that skip simulations.

power_n_calc(): Calculate the sample size needed for target ANOVA power
power_achieved_calc(): Calculate achieved ANOVA power at a fixed sample size
power_sensitivity_calc(): Calculate ANOVA effect-size sensitivity at a fixed sample size

Fixed-design simulation with explicit sample sizes, means, and SDs.

power_unbalanced(): Simulate power for a fixed unbalanced ANOVA design
cell_design(): Define cells for a means-based unbalanced ANOVA design
unbalanced_covariance(): Specify covariance for a means-based unbalanced design

Component functions for power analyses.

balanced_anova_design(): Create a balanced factorial ANOVA design specification
within_covariance(): Specify a within-subject covariance structure
means_pattern(): Define a sparse relative cell-mean pattern
design_term_means(): Build calibrated means for a design term
simulate_design_dataset(): Simulate data from a balanced ANOVA design
compute_scale_factor(): Compute the mean-deviation scaling factor from a change in partial eta squared
