statsmodels.stats.meta_analysis.CombineResults.conf_int_samples¶
- CombineResults.conf_int_samples(alpha=0.05, use_t=None, nobs=None, ci_func=None)[source]¶
confidence intervals for the effect size estimate of samples
Additional information needs to be provided for confidence intervals that are not based on normal distribution using available variance. This is likely to change in future.
- Parameters:
- alpha
float
in
(0, 1) Significance level for confidence interval. Nominal coverage is
1 - alpha
.- use_t
None
or bool If use_t is None, then the attribute use_t determines whether normal or t-distribution is used for confidence intervals. Specifying use_t overrides the attribute. If use_t is false, then confidence intervals are based on the normal distribution. If it is true, then the t-distribution is used.
- nobs
None
orfloat
Number of observations used for degrees of freedom computation. Only used if use_t is true.
- ci_func
None
orcallable
User provided function to compute confidence intervals. This is not used yet and will allow using non-standard confidence intervals.
- alpha
- Returns:
- ci_eff
tuple
of
ndarrays
Tuple (ci_low, ci_upp) with confidence interval computed for each sample.
- ci_eff
Notes
CombineResults currently only has information from the combine_effects function, which does not provide details about individual samples.
