Calculation of Satterthwaite Degrees of Freedom for Multi-Dimensional Contrast

Calculates the degree of freedom, F statistic and p value for multi-dimensional contrast. Used in df_md() if method is "Satterthwaite".

Usage

h_df_md_sat(object, contrast)

Arguments

object

(mmrm)
the MMRM fit.

contrast

(matrix)
numeric contrast matrix, if given a numeric then this is coerced to a row vector. Note that this should not include elements for singular coefficient estimates, i.e. only refer to the actually estimated coefficients.

Value

List with num_df, denom_df, f_stat and p_val (2-sided p-value).
