    Hi Samridhi, I have two questions related to Healthcare project. Request you to kindly reply soon. Thank you.

    1. If I get probability of 32% from anova() model, can I reject H0 (null Hypothesis) ?

    2. For 4/6th question, the y variable is Hospital-cost (continuous). If I use glm(0, it is thrpwing error stating Y-values must be within 0 - 1. I have used lm() and it is working. Please let me know if I can use lm() here.

    Regards,
    Sukhendu

    Hi Sukhendu,

    Following is the response to your queries:
    1. If I get probability of 32% from anova() model, can I reject H0 (null Hypothesis) ? No, any value > 5% is in retention zone.
    2. For 4/6th question, the y variable is Hospital-cost (continuous). If I use glm(0, it is thrpwing error stating Y-values must be within 0 - 1. I have used lm() and it is working. Please let me know if I can use lm() here.
    For continuous vars, we have to use linear model (lm()) and not glm. glm() is for logistic regression.

    Regards,
    Samridhi

    Hi,

    This is not an error message. This is the message we get when installing the binaries of the package. I hope the package has been successfully installed.

    Regards,
    Samridhi

    Hi,

    In this particular problem, you need not focus on the accuracy of the model. Rather, you need to find out the relationship between the variables. Please ignore if the accuracy of the model is not great, as we are not expected to build the best model here.

    Regards,
    Samridhi
