Suppose that we have a statistical model with parameter space . A null hypothesis is often stated by saying that the parameter is in a specified subset of . The alternative hypothesis is thus that is in the complement of , i.e. in , which is denoted by . The likelihood ratio test statistic for the null hypothesis is given by: where the quantity inside the brackets is called the likelihood ratio. Here, the notation refers to the WebDiagnosis in Physical Therapy Practice. Physical therapists use the diagnosis of specific conditions to guide their treatment options. Through the physiotherpy assessment, clinicians gather data to evaluate and form clinical judgements. [1] The diagnostic process begins with aquiring relevant data from the history and physical examination.
