One such application is the fitting of trend lines for a given data set so as to interpret the relationship of the variance of the parameters involved. We provide here a code in MATLAB that performs the weighted linear regression with (correlated or uncorrelated) errors in bivariate data which...
The data set has a dependent variable known asapply.It has 3 levels namely “unlikely”, “somewhat likely”, and “very likely”, coded in 1, 2, and 3 respectively. 3 being highest and 1 being lowest. This situation is best for using ordinal regression because of the presence of ordere...
Assumption #7: There should be no significant outliers, high leverage points or highly influential points, which represent observations in your data set that are in some way unusual. These can have a very negative effect on the regression equation that is used to predict the value of the depen...
In simple terms, if we need to identify a Disease (D1, D2,…, Dn) based on a set of symptoms (S1, S2,…, Sp) then from historical data, we need to identify the distribution of symptoms (S1, S2, .. Sp) for each of the disease ( D1, D2,…,Dn) and then using Bayes theo...
Assumption #6: There should be no significant outliers, high leverage points or highly influential points, which represent observations in your data set that are in some way unusual. These can have a very negative effect on the binomial logistic regression equation that is used to predict the va...
On the right, control values (green dots) are used to obtain an IC50 value. Does the generated curve align (comes near) with the data points? If the curve appears to be biphasic or non-sigmoid, then your dose-response experiment may require other non-linear regression models (3). Does ...

aIn this article, enterprise performance was measured as annual growth in savings, employees, profit and sales. Logistic regression was used to discover the factors that predict performance using the different measures of performance listed above. Table 3 presents the result of the regression analysis...
