Estimation of missing values for a factorial experiment

Description

Function to estimate missing values for factorial experiment with a CRD or a RCBD by the least squares method.

Usage

mve.f(dfr, y, factors, rep = NULL, maxp = 0.1, tol = 1e-06)

Arguments

dfr	The name of the data frame.
y	The name of the column for the variable to estimate missing values.
factors	The names of the columns that identify the factors.
rep	The name of the column that identifies the replications or blocks, default is NULL for a CRD.
maxp	Maximum allowed proportion of missing values to estimate, default is 10%.
tol	Tolerance for the convergence of the iterative estimation process.

Value

It returns a data frame with the experimental layout and columns y and y.est with the original data and the original data plus the estimated values.

Examples

# A data frame with some missing values
tmp <- asc
tmp$dm[c(3, 10, 115)] <- NA
# Estimate the missing values
mve.f(tmp, "dm", c("geno", "treat"))
