mapping_function function

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

mapping_function(x, num_major = 3, dist_minor = C(2, 2, 1),
  mapping_type = c("power"), powerh = 0)

Arguments

• x: data.frame Note the column names of the x should be in the order of major components, minor components, and no interactions are needed.
• num_major: number of major components
• dist_minor: the allocation of number of minor components nested under major components
• mapping_type: the form of the coefficient function of major components in front of corresponding minor terms. Currently only support "power"
• powerh: the power parameter used for the power function

Returns

data frame

Examples

data("pringles_fat")
data_fat = pringles_fat
h_tmp = 1.3
x = data_fat[,c("c1","c2","c3","x11","x12","x21","x22")]
mapping_function(x=x, num_major=3, dist_minor=c(2,2,1), mapping_type = c("power"), powerh=0)
