wxyz: Completing missing data of a matrix according to a model

Description

It generates an information matrix z=f(x, y). It uses a linear model to complete the cells without information.

Usage

wxyz(model, x, y, z)

Arguments

model

obtained by 'lm'

x

vector 'x'

y

vector 'y'

z

vector 'z' relation of 'x' e 'y'

Value

• model
  obtained by 'lm'
• x
  Numeric
• y
  Numeric
• z
  Numeric
