Comparing two logit or probit curves using a single parameter
From the data collected I fitted a psychometric curve (probit or logit curve), and now I want to compare the results. … "))
ddprob.2.1 <- glm(COND_2.2 ~ cnt, family = binomial(link = "probit"))
The plotted curves are shown in the image below. …

Choose best model between logit, probit and nls
100, 100)
These numbers correspond to the percentage of correct answers, under 11 different conditions (cnt):
cnt <- c(0, 82, 163, 242, 318, 390, 458, 521, 578, 628, 673)
Firstly I tried to fit a probit … models I get:
resp.mat <- as.matrix(cbind(corr/10, (100-corr)/10))
ddprob.glm1 <- glm(resp.mat ~ cnt, family = binomial(link = "logit"))
ddprob.glm2 <- glm(resp.mat ~ cnt, family = binomial(link = "probit …
