In the absence of outliers the mean estimate and type 1 error
of the two parameters were acceptable for all three models; however, the empirical standard error was much larger than the asymptotic standard error for the classical and semi-parametric models while these two types of standard error were similar in magnitude in the rank regression model.
2012) and thus provides an example of a possible type 1 error
In lending, correspondingly, a Type 1 error
would be rejecting a good loan, while a Type 2 error would be writing a bad loan, the economist said.
For example, a Type II error rate of 15 percent is associated with a Type 1 error
rate of 21 percent in 1996, while Type I error rates of more than 21 percent are associated with a 15 percent Type II error rate for the years 1997-2004.
This result should be interpreted cautiously as the type 1 error
in this study is huge.
If prophylactic use of B1 eventually turns into a type 1 error
, little will have been lost in such a failed experiment.
If we conclude from the results of a trial that 2 therapies are of different effectiveness, when in reality they are the same, we have committed what is known as a type 1 error
. The probability of making a type 1 error
is termed the alpha.
Additional threats to validity resulted from use of the .10 alpha level and three pairwise comparisons, which elevated the probability of Type 1 error
, i.e., the possibility that the observed differences resulted from chance.
The probability of rejecting the null hypothesis when it is true is called type 1 error
or alpha ([alpha]) or level of statistical significance.
However, Lee and Gurland (1977) showed analytically that the Type 1 error
rate of the one-sample t-test may differ greatly when sampling from distributions which have the same skewness and kurtosis.

In this task, the error scores are calculated by combining type 1 (when the participant completes the sentence with a word somewhat related to the target word) and type 3 errors (when the individual produces a word that fits the sentence when instructed to produce a word irrelevant to the sentence context) following the classical procedure of giving 1 point to type 1 errors
and 3 points to type 3 errors (Burgess & Shallice, 1996).
