Using a recent research study, identify and comment on the topic of Linear Regression. Tell us about the
X & Y variables identified in the study, discuss the logic that relates these variables (how X can predict Y),
the type of regression used for the study, the level of significance and how the conclusion was reached.

A linear regression model can estimate hip fracture incidence

In the article ?A linear regression model can estimate hip fracture incidence? the doctors used a simple
linear regression model to figure out the incidence of hip fractures in the region. Determining the
incidence of hip fractures was important before launching a new successful program in the community.
We know from our readings that a linear regression is a valuable tool to help businesses with strategic
planning and developing. Linear regression is also an approach for modeling the relationship between a
scalar dependent variable y and one or more explanatory variables (or independent variable) denoted X.
In linear regression, the relationships are modeled using linear predictor functions whose unknown
model parameters are estimated from the data collection (Cohen, 2003).
The analyst collected data to determine the number of hip fractures from 1994-2002 also using a linear
regression model to establish the potential hip fractures up to 2015. Following the same methods, the
same data was collected during the period of 2004-2009 in order to ascertain the proposed model
proved to be exact or not. Since the goal is forecasting, linear regression can be used to fit a predictive
model to an observed data set of y and X values. After developing such a model, if an additional value of
X is then given without its accompanying value of y, the fitted model can be used to make a prediction of
the value of y. In the data collection the y is described as the observed incidences of hip fractures and
the X is described as estimate incidences due to total number of reported fractures. The X can predict
the y because the total number of reported fractures can determine what percentage could lead to
actually having a hip fracture.
After the analysis is complete, the article reports that the results support that the estimation of hip
fracture incidence by constructing a mathematical regression model that can help health authorities to
establish early intervention strategies.
Hip fractures are a real health problem in the elderly . Before launching a program for hip fracture
prevention, knowing the incidence of hip fractures in a determined region is mandatory. In 2006 we
published in Archives of Osteoporosis a manuscript on the incidence of osteoporotic hip fractures in our
area (Salamanca, Spain) over the period 1994?2002, establishing a mathematical regression model to
estimate the number of fractures up to 2015 . Following the same methods used in this previous work
, we collected data on hip fractures during the period 2004?2009 in order to ascertain whether the
proposed model proved to be exact or not. These data are presented in Tables 1 and 2, and they show
that the incidence of osteoporotic hip fractures in 2004?2009 concurs with the estimation of our
mathematical model. Although incidence of fractures is increasing with time, it seems to reach a plateau
or even showing some decrease. Some authors have pointed out the fact that the incidence of hip
fractures is declining in the last few years [3, 4]. This change in the trend towards a decrease in hip
fracture incidence is not homogeneous and may vary among countries. In addition, the gender should
also be taken into account [5, 6]. In Spain, the data available show differences between regions ,
although the trend appears similar to our study .
