Logit Wald method of CI estimation
1 | ciLTx(x, n, alp)
|
x |
- Number of successes |
n |
- Number of trials |
alp |
- Alpha value (significance level required) |
Wald-type interval for all the given x
and n
based on the logit transformation of p
;
that is normal approximation for log(p/1-p)
A dataframe with
x |
- Number of successes (positive samples) |
LLTx |
- Logit Wald Lower limit |
ULTx |
- Logit Wald Upper Limit |
LABB |
- Logit Wald Lower Abberation |
UABB |
- Logit Wald Upper Abberation |
ZWI |
- Zero Width Interval |

prop.test and binom.test
for equivalent base Stats R functionality,
binom.confint
provides similar functionality for 11 methods,
wald2ci
which provides multiple functions for CI calculation ,
binom.blaker.limits
which calculates Blaker CI which is not covered here and
propCI
which provides similar functionality.
