Q Methodology: Summary of bootstrap results
Summarises bootstrap results for Q-sorts and statements into two tables.
qmb.summary(qmboots)
qmboots |
an object of bootstrap results, as produced by |
Returns a list with two data frames:
qsorts |
data frame with Q-sort as rows, and the following columns: the factor loadings from the standard analysis (*.std), the bootstrap (*.loa), the bootstrap SE (*.SE), the frequency of flagging (*.freq*) and the estimate of bias (*.bias). |
statements |
data frame with statements as rows, and the following columns: the z-scores from the standard analysis (*.std), from the bootstrap (*.bts), bootstrap SE (*.SE), estimate of bias of z-scores (*.bias), factor scores from the standard analysis (fsc_f*), from the bootstrap (fsc.bts.*), estimate of bias of factor scores, distinguishing and consensus statements from the standard results (see |
