getTSalpha {binseqtest} | R Documentation |
Two functions to find tsalpha
and alternative
.
getTSalpha(tsalpha = NULL, alternative = NULL, conf.level = NULL) getAlternative(tsalpha)
tsalpha |
vector of length 2 with nominal significance levels for each side, if not NULL overrides |
conf.level |
confidence level, ignored if tsalpha is not NULL |
alternative |
character, alternative hypothesis, either 'less', 'greater' or 'two.sided' |
The tsalpha
is a vector of length 2 giving the nominal error for each side
of confidence intervals. The function getTSalpha
creates a tsalpha
vector, allowing its creation either directly (non-null input for the argument tsalpha
simply outputs that same argument), or through the alternative
and conf.level
arguments.
The element tsalpha[1]
is the nominal error on the lower side, so for example if tsalpha=NULL
, alternative='greater'
, andconf.level=.95
,
then getTSalpha
outputs the vector c(0.05,0)
. In other words, if on rejection you want to conclude that θ>θ_0, then you want all the nominal
error to be on the lower side. Similarly tsalpha[2]
is the nominal error on the upper side, and tsalpha=NULL
, alternative='less'
, andconf.level=.95
,
gives c(0,0.05)
. If tsalpha=NULL
, alternative='greater'
, and conf.level=.95
, then outputs the vector c(0.025,0.025)
.
You must supply either tsalpha
or both alternative
and conf.level
.
getTSalpha
returns a tsalpha vector (see details), and getAlternative
gives the character vector for the appropriate alternative.
getTSalpha(conf.level=.95,alternative="two.sided") getAlternative(c(0,.025))
