Residuals and Least-Squares Property

9.7K
The vertical distance between the actual value of y and the estimated value of y. In other words, it measures the vertical distance between the actual data point and the predicted point on the line
If the observed data point lies above the line, the residual is positive, and the line underestimates the actual data value for y. If the observed data point lies below the line, the residual is negative, and the line overestimates the actual data value for y.

Multiple Regression

4.2K
Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Regression Analysis

8.8K
Regression analysis is a statistical tool that describes a mathematical relationship between a dependent variable and one or more independent variables.
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:

Pharmacodynamic Models: Additive and Proportional Drug Effect Model

51
Drug response models describe how pharmacological agents interact with biological systems to produce measurable effects. Baseline responses are inherent physiological activities without a drug significantly influencing the observed pharmacological outcomes. Depending on the drug response model employed, these baseline responses may combine with the drug's effect in either an additive or proportional manner.Additive Drug Response ModelIn the additive model, the drug effect is independent of the...

Regression Toward the Mean

7.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Area of Science:

  • Pediatrics
  • Public Health
  • Behavioral Science

Background:

  • Parental vaccine hesitancy is a significant public health concern impacting child immunization rates.
  • Understanding factors influencing parental vaccine decisions is crucial for developing effective interventions.

Purpose of the Study:

  • To examine the association between parents' pre-visit intentions and their children's actual vaccine acceptance.
  • To identify predictors of vaccine refusal and acceptance among parents attending pediatric visits.

Main Methods:

  • A survey was administered to parents at two pediatric practices.
  • Hierarchical logistic regression analysis was used to analyze vaccine refusal and acceptance.
  • Data were collected from a convenience sample of parents with children aged 6 weeks to 17 years.

Main Results:

  • Vaccine refusal history and pre-visit decisions explained 87% of refusals in hospital-based settings and 81% in community-based settings.
  • Over 20% of parents altered their vaccination decisions during the visit.
  • A notable number of parents who previously refused vaccines or intended to refuse ultimately accepted vaccination.

Conclusions:

  • Pre-visit parental intentions and prior vaccine refusal history are strong predictors of vaccine acceptance.
  • Pediatric visits present opportunities to influence parental vaccine decisions, with a substantial proportion of parents changing their minds.
  • Further research is needed to identify specific factors that can positively influence parental vaccine decision-making.
