The model:

Where:

b0, b1, b2, b3, b4, b5 are constants

sin(ωt) and cos(ωt) allow for seasonality

ωt=(2πt)/12

b3 is the slope

b4 allows for change in slope at t0 where t0 is the time of the intervention

t’ = 0 when t< t0

t’ = t- t0 when t≥ t0

δ(t) allows for break in curve (interruption)

δ(t)) = 0 when t< t0

δ(t)) = 1 when t≥ t0

ξt is the error term which we allow to have first order autocorrelation structure with parameter ρ

yt= b0+b1sin(ωt)+b2cos(ωt)+b3t+b4t’+b5δ(t)+ξt

Graphic design of slides: text

Slide design

• Keep it simple

• Keep it legible

• Generally, light text on a darker background projects well

• Sans serif fonts such as Arial are more easily read when projected.

Slide design

• Keep it simple

• Text is meant to be read, so ensure that slides are legible

• No hard and fast rules, but in general, light text on a darker background projects well

• Sans serif fonts such as Arial are more easily read when projected.

What do we mean when we talk about bivariate data• Data where there are two variables

• The two variables can be either categorical or numerical

• This session we are dealing with continuous bivariate data i.e. Both variables are continuous

• We have also looked at categorical bivariate data.....

..... Categorical bivariate data from the risk lecture:

• There are two binary (categorical) variables Type of statin (Baycol/other)

Whether died of rhabdomylysis

• With these data we examined the risk of death from rhabdomyolysis of Baycol compared to other statins

Baycol Other statins

Number who die from rhabdomyolysis

Number who are alive or died from other causes

Potential models: No impact at all


Potential models: Change in slope


Potential models: Break in curve


Potential models: Both change in slope and break
