This paper focuses on the study of a concrete dam whose diagnosis hypotheses have changed throughout the years according to evolution of the behavior observed.
His Gaia hypothesis, while fiercely contested, has changed the way we talk about and understand the Earth.
These adjusted odds ratios test the hypothesis that the indicator has changed between baseline and follow-up, after controlling for differences in respondent demographics between the two survey rounds.
The term "spline regression" refers to an econometric method for testing hypotheses that a time series trajectory has changed at a discrete point in time.
Notably these two studies had the lowest OR for mortality, and their exclusion, which would favor the null hypothesis, would not have changed our results significantly.
The precise nature of their relationship to birds has undergone a great deal of study, and hypotheses about that relationship have changed as large amounts of new evidence became available.
However, hypotheses about squamate phylogeny have changed radically in recent years [ 12], especially when comparing trees generated from morphological [ 13- 15] and molecular data [ 16- 20].
Because each t test is an independent test of the hypothesis that the sample means had changed in the direction predicted, we used Fisher's method of combining independent tests of a hypothesis [ 42] to test whether the overall level of change was significant.
It is probably no coincidence that another drug, Herceptin, which also goes after HER2, is one of the few medicines that is able to prolong the lives of people with advanced cancer.The stem-cell hypothesis has also changed the way people do basic research.
Thus, the linear regression model that we use in this paper was a parsimonious and convenient approximation of the reality and it is useful for testing statistically our hypothesis that social patterning of BMI had changed over time.
