`psychopy_ext.stats.``confidence`(agg, kind='sem', within=None, alpha=0.05, nsamples=None, skipna=True)

  Compute confidence of measurements, such as standard error of means (SEM) or confidence intervals (CI).

  Args: | agg
  Kwargs: | kind (‘sem’, ‘ci’, or ‘binomial’, default: ‘sem’) Warning Binomial not tested throroughly within (str or list, default: None) For repeated measures designs, error bars are too large. Specify which dimensions come from repeated measures (rows, cols, and/or subplots). It computes within-subject confidence intervals using a method by Loftus & Masson (1994) simplified by Cousinaueu (2005) with Morey’s (2008) correction. Based on Denis A. Engemann’s gist alpha (float, default: .05) For CI and binomial. Computed for single-tail, so effectively alpha/2. nsamples For binomial distribution confidence intervals if there is a single sample only (which presumably relfects the number of correct responses, i.e., successes). See Wikipedia skipna (default: True) Whether to skip NA / null values or not. Warning Not tested thoroughly
  Returns: | mean, p_yerr
