Can you use a binary variable as the dependent variable in a regression?
If your dependent variable is dummy coded (binary) then you must use a logistic regression for you analysis. There are two types; logit and probit. Both types return very similar results and your decision on which to use is based on personal preference and discipline standards. Economics and marketing tend to use probit while sociology tends to use logit.
What are the advantages and disadvantages of using scientific models?
disadvantages *not to scale *there are limitations
Which of the following types of models is generally used to predict long term events?
computer
What are the differences between qualitative and quantitative models?
distinguish between qualitative and quantitative model
What’s the difference between a generative and discriminative model?
A generative model will learn categories of data while a discriminative model will simply learn the distinction between different categories of data. Discriminative models will generally outperform generative models on classification tasks.

Tell how to get lc50 and lc90- using probit analysis in spss?
To obtain LC50 and LC90 values using probit analysis in SPSS, first, organize your data with the dose levels and the corresponding binary response (e.g., dead/alive) for each treatment group. Next, navigate to "Analyze" > "Regression" > "Probit" in SPSS, and input your variables accordingly. After running the analysis, check the output for the probit model coefficients, which can be used to calculate the LC50 and LC90 values by determining the doses corresponding to the 50% and 90% mortality probabilities, respectively. You can also use the "Probit" or "Logit" option under "Analyze" to directly estimate these lethal concentrations based on your data.
What has the author Neil Wrigley written?
Neil Wrigley has written: 'An introduction to the use of logit models in geography' -- subject(s): Geography, Logits, Mathematics
What are the assumptions of probit analysis?
The assumptions of Probit analysis are the assumption of normality and the assumption for linear regression.
How do you calculate for eid50?
The Eid50, or effective infectious dose for 50% of a population, is calculated using dose-response data, typically obtained from experiments involving a range of doses administered to a population. You plot the proportion of individuals infected or affected against the logarithm of the dose, and then fit a sigmoidal curve to the data. The Eid50 is the dose at which 50% of the population exhibits the response or infection. Statistical software or models, such as the probit or logit model, can be used to analyze the data and determine the Eid50 value.
How should you use spss for lc50?
you can use analyze <regression <probit

Methods for estimating median survival time?
Dear readers, You can use the survival analysis with Kaplan-Meier method to estimate the median lethal time using SAS or SPSS statistical packages. Someone would think to use Probit instead of Survival Analysis, but it is not recommended when you have not independent replicates (ex.: insects). Probit exerts that replicates are independent in time. Cheers, Gabriel.
How do you repair a speedometer that does not work on a 1995 Jeep Grand Cherokee?
spedo probIt could be the speed sensor located at the trans where the cable would normally be. Or your speedo head is dead. More than likely the first.
What are the three types of of models?
the three types of models are physical models,idea models and computer models.
Is there any relationship between Testors Models and Pocher Models?
testor models are testors of models and pocher models are reciprocals of tester models
What are the models of PTSD?
