precisionMeasureWithCustomDF | R Documentation |
The following function accept an arbitrary defined degree of freedom (df). This df must be inserted in gamma after the confidence level.
CIwithDF.mean(x, gamma = 0.95 )
x |
a vector of numbers, the sample data (mandatory); |
gamma |
a vector containing first a confidence level for CI (default 0.95) and
a custom degree of freedom (when unspecified, it uses |
the confidence interval (CI) where the t
value is based on the custom-set degree of freedom.
# this will issue a warning as no custom degree of freedom is provided CIwithDF.mean( c(1,2,3), gamma = 0.90) # the confidence interval of the mean for 90% confidence level CIwithDF.mean( c(1,2,3), gamma = c(0.90, 1.5) ) # uses 1.5 as df instead of 2.
