The Hosmer–Lemeshow test is a statistical test for goodness of fit and calibration for logistic regression models. It is used frequently in risk prediction models. The test assesses whether or not the observed event rates match expected event rates in subgroups of the model population.
The table shown on the right can be used in a two-sample t-test to estimate the sample sizes of an experimental group and a control group that are of equal size, that is, the total number of individuals in the trial is twice that of the number given, and the desired significance level is 0.05. [4]

Bandspass mesh FSS (left) and bandstop patch FSS (right) Equivalent circuit for patch-type bandstop FSS. The two fundamental types of FSS are shown in Fig. 2.4.1-1 to the right - the bandpass mesh-type FSS and the bandstop patch-type FSS (Metal-mesh optical filters). The equivalent circuit for a patch-type bandstop FSS is shown in Fig. 2.4.1-2.
The 5th Expeditionary Space Operations Squadron (ESOPS), originally part of the Air Force Satellite Control Facility, was provisionally established as Operating Location-A of the 750th Space Group on 1 October 1992.
Nonetheless, it has many criticisms, [5] including the fact that it has moderate intra-rater reliability (EDSS kappa values between 0.32 and 0.76 and between 0.23 and 0.58 for the individual FSs were reported), offers poor assessment of upper limb and cognitive function, and lacks linearity between score difference and clinical severity.

The 5th Space Launch Squadron was activated on 14 April 1994 at Cape Canaveral Space Force Station, Florida as part of the Space Launch Delta 45, previously 45th Space Wing.
These six battalions and the brigade staff are organized into 61 separate advisor teams that range in size from four to twelve personnel and are generally led by a post-command Captain and a Sergeant First Class. [12] Teams are organized to provide infantry, cavalry, artillery, engineer, or logistics training and support.
