"It is among the biggest contracts ever closed in the UK rail industry and will mean a step change in reliability, capacity and comfort to British passengers".
The Commercial launch of our Open Platform is a big step for us; for the Guardian's tech team in particular, it means a step change in the the technology that powers it.
It also means a step change is needed in providing more effective and efficient pathways of care, particularly for people with chronic disease, to avoid the need for costly hospital treatment.
There has to be a step change, and that means changing the delivery mechanism.
Coded values represented the variables according to the equation: {text{Xi}} = left( {{text{Xi}} - {dot{text{X}}text{i}}} right)/{text{Xi}} = 1,{ 2},{ 3} ldots {text{K,}} (1 where xi is an independent variable coded value, Xi is the independent variable's real value, X is the independent variable's real mean, and Xi is the step change value.
The most commonly investigated regime shift hypothesis is a step change in mean level using parametric or non parametric methods [25].
In addition, to test the regime shift hypothesis as a step change in mean level, we have used a parametric method based on sequential t-test analysis of regime shifts (STARS), developed by Rodionov [28] and modified by Rodionov and Overland [29].
"The good intentions of the government's Transforming Rehabilitation reforms, which meant to bring about a step change in rehabilitation by extending support from probation services to this large group of prisoners who previously received no supervision on release, have not yet been realised," says the report.
Zamba and Hawkins (2006) presented a model to estimate the time of step change in the mean vector of multivariate processes in situations where the parameters are unknown.
Niaki and Khedmati (2012) proposed a new method to derive the maximum likelihood estimator of the time of a step change in the mean vector of multivariate Poisson processes.
