bStep1 {forsearch} | R Documentation |
Derives the first set of observation numbers for forsearch in linear mixed effects models
bStep1(yesfactor, df1, df1.ls, groups, inner.rank, initial.sample,
nofactform = NULL, formulaA, randform, ycol, b.d)
yesfactor |
Logical. TRUE if there are factors in the X matrix |
df1 |
Data frame being analyzed by forward search. |
df1.ls |
List, each element of which is a factor subset of df1 |
groups |
Vector of Quoted names of group variables |
inner.rank |
Rank of X matrix of lme analysis on entire database |
initial.sample |
Number of random samples from which to take set of initial observations |
nofactform |
2-sided formula without factors |
formulaA |
Formula for all effects including factors and constructed variables |
randform |
One-sided random effects formula |
ycol |
Response column number |
b.d |
Index of point to begin diagnostic listings |
Support function, usually not called independently
Produces set of observation numbers for Step 1. Accounts for presence of factors and groups in the dataset
Presence of Observation column has no effect on outcome
