    Multivariate regression

    What is the most suitable way to assess the effect several independent ordinal variables have on a single nominal variable ?

    For example the chance of a tumour being malignant predicted by the
    1. The presence of microcalcification
    2. Definition of the margins
    3. Relative echogenicity etc

    I'm aware that if they were scale variables a Multiple linear regression analysis would do. I'm wondering what would be the best way to analyse the relative influence of these ordinal on the dependent variable.

    Any help is much appreciated.

    Re: Multivariate regression

    Is malignant variable binary (e.g., yes, no)? If so, you are looking at multivariable logistic regression.

    Re: Multivariate regression

    If the dependent variable has more than two levels and is nominal, multinominal logistic regression is suggested. If its ordered (and more than two levels) then ordinal logistic regression is suggested.
