ci.slope.prop.bs.Rd
Computes a test statistic and an adjusted Wald confidence interval for the population slope of proportions in a one-factor experimental design with a quantitative between-subjects factor.
ci.slope.prop.bs(alpha, f, n, x)
alpha level for 1-alpha confidence
vector of frequency counts of participants who have the attribute
vector of sample sizes
vector of quantitative factor values
Returns a 1-row matrix. The columns are:
Estimate - adjusted slope estimate
SE - adjusted standard error
z - z test statistic
p - two-sided p-value
LL - lower limit of the adjusted Wald confidence interval
UL - upper limit of the adjusted Wald confidence interval
