min_plot_levels

pyoptex.doe.fixed_structure.splitk_plot.utils.min_plot_levels(tppl)[source]

Computes the required number of degrees of freedom at each plot level in order to estimate all fixed effects and variances of the random effects.

Parameters

tpplnp.array(1d): The number of terms per plot level. Is the result of calling terms_per_plot_level.

Returns

reqnp.array(1d): The absolute minimum sized split^k-plot design to fit all fixed effects and estimate all variances of the random effects.
