Logistic regression analysis was performed, with the presence of VF as dependent dichotomic variable and T-score values.
Variable considered in mass appraisal modelling PRICE In Euro DATE Measured in month ELEVATOR Dichotomic variable assuming or not the presence of an elevator BALCONY Balcony measured in sq.m.
The explicative relationships between the variables were studied with a binary logistic regression model, since the dependent variable (performance) is a dichotomic variable. The independent variables are self-regulated learning, self-efficacy beliefs , and a resulting variable of the interaction between the two that enables us to determine whether self-efficacy beliefs are predictive of performance when those beliefs and self-regulated learning have high scores.
The correlations between the predictor variable and the dependent variables were analyzed, using Pearson's correlation coefficient for quantitative variables and the point-biserial correlation coefficient for dichotomic variables. Qualitative variables with more than two possible values were dichotomized (comorbidity, main diagnosis, and techniques used).
Interpretation: (a) for continuous variables, for example, the expected change in ICT per 1-unit increment in EDSS is 1.2 hours and (b) for dichotomic variables, for example, the expected change in ICT when the caregiver is a female is 3.3 hours.
The Phi ([phi]) coefficient was used to evaluate the strength of the association among dichotomic variables (DANIEL, 1990; COHEN, 1988).
All these were coded as dichotomic variables, being scored with 0 or 1 point, depending on their absence or presence.
We used the coding method "parameterization of reference cell" to code the dichotomic variables, assigning the value (0) to the categories Female (Sex), Medicine /High School), Public (Middle School Teaching Institution) and Montevideo (Location), and the value (1) for the categories Male, Engineering, Private and Inland.
