Prediction Intervals01:03

Prediction Intervals

3.3K
The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Confidence Intervals

10.2K
An unbiased point estimate is often insufficient to predict a population estimate, such as population mean or population proportion. In this scenario, a confidence interval is used. A confidence interval is an estimate similar to a  sample proportion. However, unlike the point estimate which is a single value, the confidence interval  contains a range of values. These values have lower and upper limits, known as confidence limits, and can be designated as L1 and L2, respectively.

Diabetes Mellitus: Type 2 and Gestational

4.5K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Inertial Frames of Reference01:03

Inertial Frames of Reference

8.7K
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...

Non-inertial Frames of Reference01:27

Non-inertial Frames of Reference

7.1K
A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...

Uncertainty: Confidence Intervals

10.5K
The confidence interval is the range of values around the mean that contains the true mean. It is expressed as a probability percentage. The interpretation of a 95% confidence interval, for instance, is that the statistician is 95% confident that the true mean falls within the interval. The upper and lower limits of this range are known as confidence limits. The confidence limits for the true mean are estimated from the sample's mean, the standard deviation, and the statistical factor...

Area of Science:

  • Veterinary Medicine
  • Animal Science
  • Hematology

Background:

  • Hematologic reference intervals are vital for interpreting laboratory results in swine.
  • Existing reference intervals for gestating sows are outdated, limited, or based on small sample sizes.
  • Advancements in breeding and analytical techniques necessitate updated hematologic data.

Purpose of the Study:

  • To establish updated and comprehensive hematologic reference intervals for Danish sows during mid-gestation.
  • To provide current data reflecting modern pig production and analytical capabilities.

Main Methods:

  • Blood samples were collected from 248 Danish sows at mid-gestation across five commercial herds.
  • Hematologic variables were analyzed using the Advia 2120i Hematology System.
  • Reference intervals were calculated following American Society for Veterinary Clinical Pathology guidelines.

Main Results:

  • Established reference interval for hemoglobin concentration: 103.1-145.0 g/L.
  • Established 95% reference intervals for red blood cells (4.98-7.50 × 10^12/L), hematocrit (0.32-0.47 L/L), and mean corpuscular volume (57.0-69.3 fL).
  • The determined reference intervals differ from previously reported values.

Conclusions:

  • The study provides current, reliable hematologic reference intervals for gestating Danish sows.
  • These intervals enhance the ability to prevent, diagnose, and treat diseases in sow populations.
  • The findings contribute valuable data to swine hematology and veterinary clinical pathology.
