This multiple regression research paper is mainly focused on some areas of concern. In this particular research paper, I will focus on recalling the simple type of linear regression. The other domain concentrated in this is the model for multiple regressions. The credit card data is particularly on income on the limit and the rating categorization of the women who are involved in the science Data. The regression data categorization is primarily in the fact that there are some Constance facts which are more considered in this research paper which includes the card numbers, age educational level and ethnicity balance. Focusing on the ethnicity level, the data raw is basically on different levels of ethical groups of the individuals. Following the categorization of the data, Caucasian ethnics give a sum of 333 degrees and Asians give the number of 903 among others in the same ethical level. Focusing on the different gender, students give the level of acceptance having the categories such as NO/YES. The representation of the data gives the linear regression operation which is in recalling levels. The response becomes the core factor equals intercepts plus the slope, which is the input and the error. There are some assumptions which are in this linear level of the application. The assumptions are a reality, homoscedasticity, normality, and autocorrelation. The multiple regression types of the models are well represented in the form of the formula. The response equals the functions (multiple forms of the X’s). These values are in two conditions and flows, such as raw data values, and the others are prediction values. The credit form of data is in the balance versus income and age.

The assumptions

There are some assumptions which are in addition to the models. Xi represents the independent valuation and correlation errors. In this application, the age in co-operating with the income is included in the model. There is only one type of limit given in this data representation through models. The valuables are presented in their respective codes as indicated in the data and the coefficient levels. Following the coefficient factors, the age of the individual representation in the credit card was ignored just because they show a low level of the variables as they are well compared with the period, which is nipped off from the scatter matrix. The reason why the age can safely be removed is that there is no linear correlation which occurs between the relationship and the balance. Through the rating level, the linear relation for both the limit as well as the income was removed. The removal of the ratings will be significant since it will help balance and coordinate of the multicollinearity. In this case, the logical level of the conspiracy for the credit will be highly dependent on the income of each through the credit limit. The fact that fact credit limit and the revenue results to prediction through the credit type of the card balance and C becomes (2, 2).

Removal of related values which are not linear

Following the topic and the area of concern, there are some of the variables taken out of the data. Some of the variables which are assumed to be rounded off include education, married, age-gender as well as ratings and cards for that matter. In the observation, it will be evident that the limit and the invoice have a linear form of relationship with the balance. In that case, the students who are in the binary type of factor are variables of the credit data. The best of the outfit determines 62%, and therefore, the variables used for the test of the inflation for multicollinearity. VIF is low towards the value of 10, and consequently, remarkably saved if we ignore it and its relationship with the limit and the income. The effectiveness of the multicollinearity will be void based on the fact that it will affect the model.


This paper has given the analysis of the categorized data in a researched way. The assumption of the model will always be considered constant, and the variance of the residuals will always not be met as it is supposed to be done; hence in this way, it will be beneficial to have an outlook of how the effect is the outliers in the models. In dealing with the values fitted and average, the R type of the square will adjust to the high level, the residential VS will fit well, and the bright pattern will be indicated in this matter, given that it will be distributed all around the mean. Following the information is given up, it will be sufficient for improvement of the research done on this particular level. Information given in the data is well researched and represented in this research paper, and therefore it will be all considered as helpful for data analysis.
