Functions in AHM (1.0.1)

find_condition_num

Compute the conditional number of design matrix
predict.ahm

Predict method for the fitted ahm object
mymaximin

The mymaximin function generates the matrix of maximin design points. It uses the simplex centroid design as the base design, then in a stochastics way sample the candidate design points generated by the function partition.
design_simplex_centroid_design_3_major_component

Design points for the simplex centroid design with 3 components
pringles_candidates2search

The candidate search points in the nonlinear optimization for the optimal value in the Pringles experiment
predict.cv.ahm

Predict method for the fitted cv.ahm object
mapping_function

Mapping_function is a function to add the functional coefficients of major components in front of minor components terms
summary.ahm

Summary method for the fitted ahm object
pringles_hardness

Pringles experiment data set with the Hardness as the response
pringles_fat

Pringles experiment data set with the percent of Fat as the response
expand_interactions

Expand the interaction terms for each subset group, say x11, x12, or c1, c2, c3
ahm

This is one of the main functions. The function ahm computes the proposed additive heredity model.
coef.ahm

Coefficient method for the fitted ahm object
cv.ahm

This is one of the main functions. It perform the cross validation on ahm models to select the optimal setting of hyper parameter h
check_col_correlation

Check column correlations
enlist

Create a list
coating

Photoresist-coating experiment data
coef.cv.ahm

Coefficient method for the fitted cv.ahm object
compute_aicc

compute AICc
