ANOVA

Design

ANOVA_design()

Design function used to specify the parameters to be used in simulations

print(<design_aov>) plot(<design_aov>)

Methods for design_aov objects

Power

ANOVA_power()

Simulation function used to estimate power

ANOVA_exact() ANOVA_exact2()

Simulates an exact dataset (mu, sd, and r represent empirical, not population, mean and covariance matrix) from the design to calculate power

emmeans_power()

Compute power for emmeans contrasts

plot_power()

Methods for ancova_power objects

Justify your Alpha

Compromise functions for finding an optimal alpha level

alpha_standardized()

Compute standardized alpha level based on unstandardized alpha level and the number of observations N.

ANOVA_compromise()

Justify your alpha level by minimizing or balancing Type 1 and Type 2 error rates for ANOVAs.

optimal_alpha()

Justify your alpha level by minimizing or balancing Type 1 and Type 2 error rates.

p_standardized()

Compute standardized alpha level based on unstandardized alpha level and the number of observations N.

power_standardized_alpha()

Optimizing function to achieve desired power based on a standardized alpha level.

print(<opt_alpha>) plot(<opt_alpha>)

Methods for opt_alpha objects

Sensitivity Functions

morey_plot.ttest() morey_plot.ftest()

Plot out power sensitivity plots for t or F tests

Other Power Functions

power.ftest()

Power Calculations for an F-test

power_oneway_ancova()

Power Calculations for a one-way ANCOVA

power_oneway_between()

Analytic power calculation for one-way between designs.

power_oneway_within()

Analytic power calculation for one-way within designs.

power_twoway_between()

Analytic power calculation for two-way between designs.

power_threeway_between()

Analytic power calculation for three-way between designs.

mu_from_ES()

Convenience function to calculate the means for between designs with one factor (One-Way ANOVA). Can be used to determine the means that should yield a specified effect sizes (expressed in Cohen's f).
