Col

class pyoptex.doe.constraints.Col(col, factor, colstart=0)

The base Column object to represent a constraint. If this object is contained in a variable called constraint, use constraint.func() to retrieve a function which can evaluate the specified constraints on a decoded design matrix. Use constraint.encode() to retrieve a function which can evaluate the specified constraints on an encoded design matrix.

Attributes

colfloat or int or string

Meaning depends on the value of factor.

factorNone or Factor

If None, this column represents a simple constant and col represents the constant value. Otherwise, it represents the column and the attribute col represents the index of the factor in the design.

colstartint

The start of the column in the encoded design matrix.

is_constantbool

Whether this column is a constant

is_categoricalbool

Whether this is a categorical column

__init__(col, factor, colstart=0)

Methods

Col.encode()	Retrieves a function to evaluate the encoded design matrix.
Col.func()	Retrieves a function to evaluate the decoded design matrix.
