Likert scale, Thurstone scale and Guttman scale
to deal with qualitative data are explained in chapter ten.
The effect of the Guttman scale on hospital choice indicates that beneficiaries attach a positive value to greater scope of service, holding all other factors constant.
Since size and Guttman scale tend to be correlated ([R.
The Guttman scale is based on the principle of cumulative scaling, which takes advantage of the tendency of hospitals to acquire service capabilities in a predictable sequence.
We used a Guttman scale to measure scope-of-service capacity, and also tested for effects of hospital size and teaching status.
This highlights the importance of having the overall data set closely approximate a perfect Guttman scale, in order to be able to make this inference.
We also examined the possibility that the Guttman scale might not be the most appropriate technique for examining the relationship between average inflation and the transparency indicators collected as part of the FJMRS survey.
The second alternative to the existing Guttman scale involved creating a matrix of dummy variables, each of which takes a value of 1 for a particular range of values of the Guttman scale.
In addition to hospital bed size, a Guttman scale was used to reflect the availability of more complex services and to account for the tendency of hospitals to acquire services from less to more complex.
The American Hospital Association (AHA) annual hospital survey data on hospital services were used to create a Guttman scale of service capacity as discussed later.
He looks at the Guttman scale
, the imperfect cumulative scale, confirmation or exploration, an example of a cumulative scale: American religious beliefs, the probabilistic dominance model: monotome homogeneity and double monotonicity, cumulative scaling with polytomous items, and remaining issues.
During development, Lyle (1981) used Guttman scale
analysis to ensure that items were truly hierarchical.
