Value

List with components

TE

statistic

Test statistic (either z-score or t-score)

p

level

The confidence level required

df

Degrees of freedom (t-distribution)

Arguments

TE

Estimated treatment effect.

seTE

Standard error of treatment estimate.

level

The confidence level required.

df
