z_tests_cfa {confreq} | R Documentation |
Calculates the Chi-square approximation to the z-test and the binomial approximation to the z-test.
z_tests_cfa(observed, expected, ccor = FALSE, ntotal = sum(observed))
observed |
a vector giving the observed frequencies. |
expected |
a vector giving the expected frequencies. |
ccor |
either a logical (TRUE / FALSE) determining wether to apply a continuity correction or not to the Binomial Approximation of the z-Test. When set to |
ntotal |
optional a numeric giving the total number of observations. By default ntotal is calculated as |
An continuity correction can be applied to the binomial approximation – see argument ccor
.
