a fitted threshpt object produced by threshpt()

...

Not used

Value

summary.threshpt produces a list of summary informations for a fitted threshpt object with components

Formula

the formula which is used in the threshpt function

Best fit

estimated parameter coefficients of model with the minimum deviance

Deviance

deviance of a fitted threshpt model

Threshold

threshold value of the model with the minimum deviance

Examples

# read the Seoul data set and create lag variables
data(mort)
seoul = read6city(mort, 11)
seoul_lag = lagdata(seoul, c("meantemp", "mintemp", "meanpm10", "meanhumi"), 5)

# find a optimal threshold and conduct piecewise linear regression
mythresh = threshpt(nonacc ~ meantemp_m3 + meanpm10_m2 +  meanhumi + ns(sn, 4*10) + factor(dow), 
			     expvar = "meantemp_m3", family = "poisson", data = seoul_lag,
			     startrng = 23, endrng = 33, searchunit = 0.2)

# provide summary informations
summary(mythresh)
