Bingen is situated just southeast of the Rhine knee at the Bingen Forest ( Binger Wald – actually a low mountain range ), which rises west of the town.

Lillian D. Wald ( March 10, 1867 – September 1, 1940 ) was a nurse ; social worker ; public health official ; teacher ; author ; editor ; publisher ; activist for peace, women's, children's and civil rights ; and the founder of American community nursing.

In 1893 after a period of working at the New York Juvenile Asylum – an orphanage where children were kept and conditions were poor – Wald started to teach a home class on nursing for poor immigrant families on the Lower East Side ( New York ).

While a part-time graduate student, Wolfowitz met Abraham Wald, with whom he collaborated in numerous joint papers in the field of mathematical statistics.

* The Wald – Wolfowitz runs test tests for the number of bit transitions between 0 bits, and 1 bits, comparing the observed frequencies with expected frequency of a random bit sequence.

In logistic regression, there are a couple of different tests designed to assess the significance of an individual predictor, most notably, the likelihood ratio test and the Wald statistic.

* The Wald test can be evaluated against a chi-squared distribution

The F-test is a Wald test.

It can also be used in the formulation of test statistics, such as the Wald test.

The likelihood ratio test, the Wald test, and the Score test are asymptotically equivalent tests of hypotheses.

The Wald test is a parametric statistical test named after the Transylvanian statistician Abraham Wald with a great variety of uses.

Whenever a relationship within or between data items can be expressed as a statistical model with parameters to be estimated from a sample, the Wald test can be used to test the true value of the parameter based on the sample estimate.

Say is the average increase in shoe size for upper-class people compared to middle-class people: then the Wald test can be used to test whether is 0 ( in which case social class has no association with shoe size ) or non-zero ( shoe size varies between social classes ).

In the Wald test, the economist uses the estimate and an estimate of variability ( see below ) to draw conclusions about the unobserved true.

Or, for a medical example, suppose smoking multiplies the risk of lung cancer by some number R: then the Wald test can be used to test whether R = 1 ( i. e. there is no effect of smoking ) or is greater ( or less ) than 1 ( i. e. smoking alters risk ).

A Wald test can be used in a great variety of different models including models for dichotomous variables and models for continuous variables.

Under the Wald statistical test, the maximum likelihood estimate of the parameter ( s ) of interest is compared with the proposed value, with the assumption that the difference between the two will be approximately normally distributed.

A common use for this is to carry out a Wald test on a categorical variable by recoding it as several dichotomous variables.

Usually the Wald test and the likelihood ratio test give very similar conclusions ( as they are asymptotically equivalent ), but very rarely, they disagree enough to lead to different conclusions: the researcher finds him / herself asking, or being asked, why the p-value is significant when the confidence interval includes 0, or why the p-value is not significant when the confidence interval excludes 0.

* 1943 – Paul Wolfowitz, American politician

The second child of Jacob Wolfowitz ( 1910 – 1981 ) and Lillian Dundes, Paul Wolfowitz was born in Brooklyn, New York, into a Polish Jewish immigrant family, and grew up mainly in Ithaca, New York, where his father was a professor of statistical theory at Cornell University.

" Dewi Fortuna Anwar, a foreign policy adviser to B J Habibie, Suharto's successor as head of state ( 1998 – 1999 ), stated " that Wolfowitz was a competent and popular envoy.
